Chain A,B   (PPSC_MYCTU | P96202)
molecular function
    GO:0004315    3-oxoacyl-[acyl-carrier-protein] synthase activity    Catalysis of the reaction: acyl-[acyl-carrier protein] + malonyl-[acyl-carrier protein] = 3-oxoacyl-[acyl-carrier protein] + CO2 + [acyl-carrier protein].
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
    GO:0031177    phosphopantetheine binding    Interacting selectively and non-covalently with phosphopantetheine, the vitamin pantetheine 4'-(dihydrogen phosphate).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0071766    Actinobacterium-type cell wall biogenesis    A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a cell wall of the type found in Actinobacteria. The cell wall is the rigid or semi-rigid envelope lying outside the cell membrane. Actinobacterial cell walls contain characteristic mycolic acids, of which some are covalently linked to the cell wall peptidoglycan and others accumulate at the cell surface.
    GO:0071770    DIM/DIP cell wall layer assembly    The aggregation, arrangement and bonding together of a set of components, including (phenyl)phthiocerol, phthiodiolone, phthiotriol dimycocerosate and diphthioceranate, to form the DIM/DIP layer of the Actinobacterium-type cell wall.
    GO:0006633    fatty acid biosynthetic process    The chemical reactions and pathways resulting in the formation of a fatty acid, any of the aliphatic monocarboxylic acids that can be liberated by hydrolysis from naturally occurring fats and oils. Fatty acids are predominantly straight-chain acids of 4 to 24 carbon atoms, which may be saturated or unsaturated; branched fatty acids and hydroxy fatty acids also occur, and very long chain acids of over 30 carbons are found in waxes.
    GO:0006631    fatty acid metabolic process    The chemical reactions and pathways involving fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis.
    GO:0006629    lipid metabolic process    The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
    GO:0097041    phenolic phthiocerol biosynthetic process    The chemical reactions and pathways resulting in the formation of phenolic phthiocerol, a phthiocerol derivative having a 4-hydroxyphenyl substituent at the 29-position.
    GO:0097040    phthiocerol biosynthetic process    The chemical reactions and pathways resulting in the formation of phthiocerol, a lipid-based 1,3-glycol consisting of (3S,4R)-3-methoxy-4-methylnonacosane having (9R)- and (11S)-hydroxy substituents.
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.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
    GO:0034081    polyketide synthase complex    A protein complex that carries out enzymatic reactions involved in the biosynthesis of polyketides, any of a diverse group of natural products synthesized via linear poly-beta-ketones.
