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.

Diacylglycerol acyltransferase/mycolyltransferase Ag85B; The antigen 85 proteins (FbpA, FbpB, FbpC) are responsible for the high affinity of mycobacteria for fibronectin, a large adhesive glycoprotein, which facilitates the attachment of M.tuberculosis to murine alveolar macrophages (AMs). They also help to maintain the integrity of the cell wall by catalyzing the transfer of mycolic acids to cell wall arabinogalactan and through the synthesis of alpha,alpha- trehalose dimycolate (TDM, cord factor). They catalyze the transfer of a mycoloyl residue from one molecule of alpha,alpha-treha [...]

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.

Rv3838c, (MTCY01A6.31), len: 321 aa. PheA,prephenate dehydratase (see citation below), equivalent to Q9CDC4|PHEA|ML0078 putative prephenate dehydratase from Mycobacterium leprae (322 aa), FASTA scores: opt: 1690,E(): 1.3e-93, (84.25% identity in 311 aa overlap). Also highly similar to others e.g. P10341|PHEA_CORGL from Corynebacterium glutamicum (Brevibacterium flavum) (315 aa), FASTA scores: opt: 843, E(): 4e-43, (45.8% identity in 308 aa overlap); Q9ZBX0|SCD78.29c from Streptomyces coelicolor (310 aa), FASTA scores: opt: 820, E(): 9.2e-42,(46.45% identity in 312 aa overlap); Q44104|P [...]

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 [...]

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

Possible anthranilate synthase component II TrpG (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.

Probable resuscitation-promoting factor RpfC; Factor that stimulates resuscitation of dormant cells. Has peptidoglycan (PG) hydrolytic activity. Active in the pM concentration range. Has little to no effect on actively-growing cells. PG fragments could either directly activate the resuscitation pathway of dormant bacteria or serve as a substrate for endogenous Rpf, resulting in low molecular weight products with resuscitation activity. Belongs to the transglycosylase family. Rpf subfamily.

3-dehydroquinate dehydratase AroD (AROQ) (3-dehydroquinase) (type II dhqase); Catalyzes a trans-dehydration via an enolate intermediate.
