Coproporphyrinogen III oxidase; Involved in the heme biosynthesis. Catalyzes the aerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen- IX.

Isochorismatase; 2,3 dihydro-2,3 dihydroxybenzoate synthase; catalyzes the formation of 2,3 dihydro-2,3 dihydroxybenzoate and pyruvate from isochorismate; with Ent DEF is involved in enterobactin synthesis; Derived by automated computational analysis using gene prediction method: Protein Homology.

Hypoxanthine oxidase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Glycerol-3-phosphate dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the NAD-dependent glycerol-3-phosphate dehydrogenase family.

Aldo/keto reductase; Derived by automated computational analysis using gene prediction method: Protein Homology.

NAD synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.

Glucosamine-6-phosphate deaminase; Catalyzes the reversible isomerization-deamination of glucosamine 6-phosphate (GlcN6P) to form fructose 6-phosphate (Fru6P) and ammonium ion.

biotin--[acetyl-CoA-carboxylase] synthetase; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.

Nicotinate phosphoribosyltransferase; Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP; Belongs to the NAPRTase family.
