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.

Conserved protein; Oxidase that catalyzes the conversion of cysteine to 3- oxoalanine on target proteins. 3-oxoalanine modification, which is also named formylglycine (fGly), occurs in the maturation of arylsulfatases and some alkaline phosphatases that use the hydrated form of 3- oxoalanine as a catalytic nucleophile.

Probable adenosylhomocysteinase SahH (S-adenosyl-L-homocysteine hydrolase) (adohcyase); May play a key role in the regulation of the intracellular concentration of adenosylhomocysteine.

Probable UDP-N-acetylglucosamine pyrophosphorylase GlmU; Catalyzes the last two sequential reactions in the de novo biosynthetic pathway for UDP-N-acetylglucosamine (UDP-GlcNAc). The C- terminal domain catalyzes the transfer of acetyl group from acetyl coenzyme A to glucosamine-1-phosphate (GlcN-1-P) to produce N- acetylglucosamine-1-phosphate (GlcNAc-1-P), which is converted into UDP-GlcNAc by the transfer of uridine 5-monophosphate (from uridine 5- triphosphate), a reaction catalyzed by the N-terminal domain.

Probable dioxygenase; Alpha-ketoglutarate-dependent sulfate ester dioxygenase, which oxidizes medium-chain alkyl-sulfate esters. Shows preference for 2-ethylhexyl sulfate (2-EHS) in vitro, leading to the formation of succinate and 2-ethylhexanal. Has likely a role in sulfate scavenging in vivo.

Rv0711, (MTCY210.30), len: 787 aa. Possible atsA,arylsulfatase, similar to others e.g. P51691|ARS_PSEAE arylsulfatase from Pseudomonas aeruginosa (532 aa), FASTA scores: opt: 439, E(): 2.9e-21, (30.8% identity in 552 aa overlap); etc. Also similar to other hypothetical arylsulfatases from Mycobacterium tuberculosis e.g. Rv3299c, Rv0663, etc. Contains PS00523 Sulfatases signature 1, and PS00149 Sulfatases signature 2. Belongs to the sulfatase family.

Possible hydrolase; Rv3077, (MTCY22D7.04c), len: 603 aa. Possible hydrolase, with some similarity to variety of hydrolases (aryl- and steryl sulfatases principaly) e.g. Q45087|PEHA phosphonate monoester hydrolase from Burkholderia caryophylli (514 aa), FASTA scores: opt: 239, E(): 7.2e-07,(23.95% identity in 413 aa overlap); Q9I1E5|PA2333 probable sulfatase from Pseudomonas aeruginosa (538 aa), FASTA scores: opt: 231, E(): 2.3e-06, (28.1% identity in 516 aa overlap); P31447|YIDJ_ECOLI|B3678 putative sulfatase from Escherichia coli (497 aa), FASTA scores: opt: 222, E(): 7.4e-06, (27.7% [...]

PE-PGRS family protein PE_PGRS5; Involved in endoplasmic reticulum (ER) stress-mediated apoptosis through human Toll-like receptor 4 (TLR4) signaling pathway. Localizes to the host ER, leading to ER stress, disruption of intracellular Ca(2+) homeostasis and increase of nitric oxide (NO) and reactive oxygen species (ROS) levels. Stress response results in caspase-8 activation and apoptosis of macrophage cells. Apoptosis may lead to dissemination of the bacteria, thereby spreading the disease. Belongs to the mycobacterial PE family. PGRS subfamily.
