Anthranilate synthase component I TrpE (glutamine amidotransferase); Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly [...]

Chorismate mutase; Catalyzes the Claisen rearrangement of chorismate to prephenate. May play some role in the pathogenicity.

Probable chorismate synthase AroF (5-enolpyruvylshikimate-3-phosphate phospholyase); Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.

Prephenate dehydrogenase TyrA (PDH) (hydroxyphenylpyruvate synthase); Catalyzes the NAD(+)-dependent conversion of prephenate to p- hydroxyphenylpyruvate, with the elimination of carbon dioxide. Is a key regulatory enzyme in tyrosine biosynthesis. Displays no chorismate mutase (CM) activity, in contrast to TyrA from E.coli and some other bacteria, that are bifunctional and possess a CM domain.

Probable isochorismate synthase EntC (isochorismate hydroxymutase) (enterochelin biosynthesis); Catalyzes the conversion of chorismate to isochorismate.

Possible transcriptional regulatory protein (possibly MarR-family); Rv0880, (MTCY31.08), len: 143 aa. Possible transcriptional regulator, MarR family, equivalent to MLCB57_15|O3306|NP_302411.1|NC_002677 putative MarR-family protein from Mycobacterium leprae (143 aa), FASTA scores: opt: 818, E(): 0, (89.5% identity in 143 aa overlap).

Isochorismate synthase MbtI; Involved in the incorporation of salicylate into the virulence-conferring salicylate-based siderophore mycobactin. Catalyzes the initial conversion of chorismate to yield the intermediate isochorismate (isochorismate synthase activity), and the subsequent elimination of the enolpyruvyl side chain to give salicylate (isochorismate pyruvate-lyase activity). In the absence of magnesium, MbtI displays a chorismate mutase activity and converts chorismate to prephenate.
