Asymmetric Unit(hide GO term definitions)
Chain A   (RHAD_ECOLI | P32169)
molecular function
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008994    rhamnulose-1-phosphate aldolase activity    Catalysis of the reaction: L-rhamnulose 1-phosphate = glycerone phosphate + (S)-lactaldehyde.
biological process
    GO:0019323    pentose catabolic process    The chemical reactions and pathways resulting in the breakdown of a pentose, any monosaccharide with a chain of five carbon atoms in the molecule.
    GO:0019301    rhamnose catabolic process    The chemical reactions and pathways resulting in the breakdown of rhamnose, the hexose 6-deoxy-L-mannose.
    GO:0019299    rhamnose metabolic process    The chemical reactions and pathways involving rhamnose, the hexose 6-deoxy-L-mannose. Rhamnose occurs commonly as a compound of plant glycosides, in polysaccharides of gums and mucilages, and in bacterial polysaccharides. It is also a component of some plant cell wall polysaccharides and frequently acts as the sugar components of flavonoids.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
