ProductConserved hypothetical protein
CommentsRv3730c, (MTV025.078c), len: 346 aa. Conserved hypothetical protein, highly similar to Q9XAM1|SC4C6.19 hypothetical 38.5 KDA protein from Streptomyces coelicolor (341 aa), FASTA scores: opt: 1313, E(): 2.2e-75, (59.25% identity in 336 aa overlap); and similar to C-terminal end of putative ATP-dependent DNA ligases e.g. BAB49297|MLL2077 from Rhizobium loti (Mesorhizobium loti) (833 aa), FASTA scores: opt: 550, E(): 5.3e-27, (31.3% identity in 294 aa overlap); and BAB54816|MLL9625 from Rhizobium loti (Mesorhizobium loti) plasmid pMLb (883 aa) FASTA scores: opt: 492, E(): 2.5e-23, (33.7% identity in 291 aa overlap); etc. Also similar to the hypothetical proteins e.g. Q9ZC15|SC1E6.07 hypothetical 34.9 KDA protein from Streptomyces coelicolor (319 aa) FASTA scores: opt: 537, E(): 1.5e-26, (34.95% identity in 292 aa overlap); Q9XAF7|SC6G9.25 hypothetical 32.1 KDA protein from Streptomyces coelicolor (293 aa), FASTA scores: opt: 474, E(): 1.3e-22, (33.75% identity in 302 aa overlap); etc. Also highly similar to P95226|Rv0269c|MTCY06A4.13c hypothetical 44.0 KDA protein from Mycobacterium tuberculosis (397 aa), FASTA scores: opt: 940, E(): 7.7e-52, (50.3% identity in 312 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). Translational start site supported by proteomics data (See Kelkar et al., 2011).
Mutationnon essential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website
