Rv0508, (MTCY20G9.35), len: 97 aa. Conserved hypothetical protein, showing similarity with T36269|5123666|CAB45355.1|AL079345 probable redoxin from Streptomyces coelicolor (101 aa), FASTA scores: opt: 160,E(): 3.4e-05, (33.3% identity in 75 aa overlap); and E81943|NMA0966 probable thioredoxin from Neisseria meningitidis group a strain Z2491 (77 aa).

Sulfate-transport ATP-binding protein ABC transporter CysA1; Part of the ABC transporter complex CysAWTP involved in sulfate/thiosulfate import. Responsible for energy coupling to the transport system.

Probable sulfate-transport integral membrane protein ABC transporter CysT; Part of the ABC transporter complex (TC 3.A.1.6.1) involved in sulfate/thiosulfate import.

Conserved protein; Rv0504c, (MTCY20G9.31c), len: 166 aa. Conserved protein, equivalent to P54879|Y504_MYCLE|ML2425 hypothetical 18.7 KDA protein from Mycobacterium leprae (166 aa), FASTA scores: opt: 884, E(): 0, (83.1% identity in 166 aa overlap); and highly similar to other proteins from Mycobacterium leprae. Also highly similar to CAB77410.1|AL160431|SCD82.07 hypothetical protein from Streptomyces coelicolor (150 aa). Also similar to M. tuberculosis hypothetical proteins Rv0635|H70612 (158 aa); and Rv0637|B70613 (166 aa); Belongs to the UPF0336 family.

Cyclopropane mycolic acid synthase 2; Catalyzes the formation of trans cyclopropanated ketomycolate or methoxymycolate through the conversion of a double bond to a cyclopropane ring at the proximal position of an oxygenated mycolic acid via the transfer of a methylene group from S-adenosyl-L- methionine. In the absence of MmaA2, CmaA2 has a non-specific cis- cyclopropanating activity and is able to catalyze the conversion of a double bond to a cis cyclopropane ring at the distal position of an alpha mycolic acid. Cyclopropanated mycolic acids are key factors participating in cell envel [...]

Probable phosphoserine phosphatase SerB2 (PSP) (O-phosphoserine phosphohydrolase) (pspase); Catalyzes the dephosphorylation of O-phospho-L-serine into L- serine, a step in the L-serine biosynthetic pathway. Exhibits high specificity for L-phosphoserine compared to substrates like L-phosphothreonine (5% relative activity) and L-phosphotyrosine (1.7% relative activity). Belongs to the HAD-like hydrolase superfamily. SerB family.

Probable D-3-phosphoglycerate dehydrogenase SerA1 (PGDH); Catalyzes the reversible oxidation of 3-phospho-D-glycerate to 3-phosphonooxypyruvate, the first step of the phosphorylated L- serine biosynthesis pathway. Also catalyzes the reversible oxidation of 2-hydroxyglutarate to 2-oxoglutarate.

Probable cyclase HisF; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit (By similarity).

Serine hydroxymethyltransferase GlyA2 (serine methylase 2) (SHMT 2); Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism. Thus, is able to catalyze the cleavage of L- allo-threonine; Belongs to the SHMT family.
