ProductConserved hypothetical protein
CommentsRv0496, (MTCY20G9.22), len: 328 aa. Conserved hypothetical protein, highly similar to S72894|467046|AAA17230.1|U00018 exopolyphosphatase ppx from Mycobacterium leprae (406 aa), FASTA scores: opt: 1902, E(): 0, (86.6% identity in 343 aa overlap); and P54882|Y496_MYCLE|ML2434|13094008|CAC31951.1|AL583925 hypothetical 36.2 KDA protein from Mycobacterium leprae (339 aa). Also highly similar to hypothetical proteins and exopolyphosphatases e.g. Q9X8H1|Y715_STRCO|SCE7.15c hypothetical protein from Streptomyces coelicolor (309 aa). C-terminal region similar to CGU31224_1|Q46054 protein similar to ppx gene product of Mycobacterium leprae from Cornybacterium glutamicum (140 aa), FASTA scores: opt: 615, E(): 2.7e-33, (70.9% identity in 134 aa overlap).

Functional categoryconserved hypotheticals
Prediction based on GO and InterPro: intermediary metabolism and respiration (See Mazandu and Mulder, 2012)

ProteomicsIdentified 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 whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website
