General annotation
FunctionInvolved in de novo phospholipid biosynthesis; glycerol-3 phosphate formation [catalytic activity: SN-glycerol 3-phosphate + NAD(P)(+) = glycerone phosphate + NAD(P)H].
ProductProbable glycerol-3-phosphate dehydrogenase [NAD(P)+] GpdA2 (NAD(P)H- dependent glycerol-3-phosphate dehydrogenase)
CommentsRv2982c, (MTCY349.05), len: 334 aa. Probable gpdA2 (alternate gene name: gpsA), glycerol-3-phosphate dehydrogenase [NAD(P)+], equivalent to Q9CBR9|GPDA_MYCLE glycerol-3-phosphate dehydrogenase [NAD(P)+] from Mycobacterium leprae (349 aa), FASTA scores: opt: 1686, E(): 1.7e-95, (77.95% identity in 349 aa overlap). Also highly similar to others e.g. Q9ZBS0|GPDA_STRCO from Streptomyces coelicolor (336 aa), FASTA scores: opt: 1165, E(): 9.8e-64, (56.25% identity in 327 aa overlap); P46919|GPDA_BACSU from Bacillus subtilis (345 aa), FASTA scores: opt: 872, E(): 7.5e-46, (44.9% identity in 325 aa overlap); P37606|GPDA_ECOLI|GPSA|B3608|Z5035|ECS4486. from Escherichia coli strain O157:H7 and K12 (339 aa), FASTA scores: opt: 799, E(): 2.1e-41, (42.9% identity in 331 aa overlap); etc. Also highly similar to O53761|GPD2_MYCTU probable glycerol-3-phosphate dehydrogenase from Mycobacterium tuberculosis (341 aa), FASTA scores: opt: 740, E(): 8.4e-38, (40.35% identity in 322 aa overlap). Belongs to the NAD-dependent glycerol-3-phosphate dehydrogenase family.

ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate; enriched in the membrane fraction and predicted N-terminal signal peptide is uncleaved (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
