General annotation
FunctionInvolved in hexose monophosphate shunt (pentose phosphate pathway) [catalytic activity: 6-phospho-D-gluconate + NADP+ = D-ribulose 5-phosphate + CO2 + NADPH].
ProductProbable 6-phosphogluconate dehydrogenase Gnd1
CommentsRv1844c, (MTCY359.29), len: 485 aa. Probable gnd1, 6-phosphogluconate dehydrogenase. Similar to others e.g. 6PGD_ECOLI|P00350 from Escherichia coli (468 aa), FASTA scores: opt: 1661, E(): 0, (53.6% identity in 466 aa overlap); etc. Also similar to Rv1122|MTCY22G8.11|gnd2 probable 6-phosphogluconate dehydrogenase, decarboxylating from Mycobacterium tuberculosis (340 aa), FASTA score: (33.0% identity in 351 aa overlap). Note that Rv1844c is most similar to gnd's from Gram negative organisms, while Rv1122|MTCY22G8.11|gnd2 is most similar to gnd's from Gram positive organisms. Belongs to the 6-phosphogluconate dehydrogenase family.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 and 90 days (See Kruh et al., 2010).
MutantDisruption of this gene provides a growth advantage 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
