Asymmetric Unit(hide GO term definitions)

Chain A,C (MALE_ECOLI | P0AEX9)

molecular function
	GO:1901982	maltose binding	Interacting selectively and non-covalently with maltose.
	GO:0005363	maltose transmembrane transporter activity	Enables the transfer of maltose from one side of the membrane to the other. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the enzymatic breakdown of glycogen and starch.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0005215	transporter activity	Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of or within a cell, or between cells.
biological process
	GO:0008643	carbohydrate transport	The directed movement of carbohydrate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Carbohydrates are any of a group of organic compounds based of the general formula Cx(H2O)y.
	GO:0060326	cell chemotaxis	The directed movement of a motile cell guided by a specific chemical concentration gradient. Movement may be towards a higher concentration (positive chemotaxis) or towards a lower concentration (negative chemotaxis).
	GO:0006974	cellular response to DNA damage stimulus	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism.
	GO:0034289	detection of maltose stimulus	The series of events in which a maltose stimulus is received by a cell and converted into a molecular signal.
	GO:0042956	maltodextrin transport	The directed movement of maltodextrin, any polysaccharide of glucose residues in beta-(1,4) linkage, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0015768	maltose transport	The directed movement of maltose into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Maltose is the disaccharide 4-O-alpha-D-glucopyranosyl-D-glucopyranose, an intermediate in the catabolism of glycogen and starch.
	GO:0006810	transport	The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
	GO:0043190	ATP-binding cassette (ABC) transporter complex	A complex for the transport of metabolites into and out of the cell, typically comprised of four domains; two membrane-associated domains and two ATP-binding domains at the intracellular face of the membrane, that form a central pore through the plasma membrane. Each of the four core domains may be encoded as a separate polypeptide or the domains can be fused in any one of a number of ways into multidomain polypeptides. In Bacteria and Archaebacteria, ABC transporters also include substrate binding proteins to bind substrate external to the cytoplasm and deliver it to the transporter.
	GO:0055052	ATP-binding cassette (ABC) transporter complex, substrate-binding subunit-containing	A complex for the transport of metabolites into the cell, consisting of 5 subunits: two ATP-binding subunits, two membrane spanning subunits, and one substrate-binding subunit. In organisms with two membranes, the substrate-binding protein moves freely in the periplasmic space and joins the other subunits only when bound with substrate. In organisms with only one membrane the substrate-binding protein is tethered to the cytoplasmic membrane and associated with the other subunits. Transport of the substrate across the membrane is driven by the hydrolysis of ATP.
	GO:1990060	maltose transport complex	Protein complex facilitating ATP-dependent maltose transport through inner cell membrane (periplasm to cytoplasm) in Gram-negative bacteria. In E. coli the system is composed of a periplasmic maltose-binding protein (MBP), two integral membrane proteins, MalF and MalG, and two copies of the cytoplasmic ATP-binding cassette MalK.
	GO:0030288	outer membrane-bounded periplasmic space	The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
	GO:0042597	periplasmic space	The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).

Chain B,D (RNHPH_MYCTU | P9WLH5)

molecular function
	GO:0071667	DNA/RNA hybrid binding	Interacting selectively and non-covalently with a RNA/DNA hybrid.
	GO:0004523	RNA-DNA hybrid ribonuclease activity	Catalysis of the endonucleolytic cleavage of RNA in RNA-DNA hybrids to 5'-phosphomonoesters.
	GO:0043755	alpha-ribazole phosphatase activity	Catalysis of the reaction: alpha-ribazole 5'-phosphate + H(2)O = alpha-ribazole + phosphate.
	GO:0032296	double-stranded RNA-specific ribonuclease activity	Catalysis of the hydrolysis of phosphodiester bonds in double-stranded RNA molecules.
	GO:0003676	nucleic acid binding	Interacting selectively and non-covalently with any nucleic acid.
biological process
	GO:0006401	RNA catabolic process	The chemical reactions and pathways resulting in the breakdown of RNA, ribonucleic acid, one of the two main type of nucleic acid, consisting of a long, unbranched macromolecule formed from ribonucleotides joined in 3',5'-phosphodiester linkage.
	GO:0090501	RNA phosphodiester bond hydrolysis	The RNA metabolic process in which the phosphodiester bonds between ribonucleotides are cleaved by hydrolysis.
	GO:0090502	RNA phosphodiester bond hydrolysis, endonucleolytic	The chemical reactions and pathways involving the hydrolysis of internal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides.
	GO:0009236	cobalamin biosynthetic process	The chemical reactions and pathways resulting in the formation of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom.
	GO:0016311	dephosphorylation	The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.
cellular component
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

Chain B,D (Y2228_MYCTO | P9WLH4)

biological process
	GO:0090502	RNA phosphodiester bond hydrolysis, endonucleolytic	The chemical reactions and pathways involving the hydrolysis of internal 3',5'-phosphodiester bonds in one or two strands of ribonucleotides.
