General annotation
Gene namehisH
Rv numberRv1602
FunctionHistidine biosynthesis pathway (fifth step). Catalyzes an amidotransferase reaction that generates imidazole-glycerol phosphate and 5-aminoimidazol-4-carboxamide ribonucleotide, which is used for purine synthesis.
ProductProbable amidotransferase HisH
CommentsRv1602, (MTCY336.02c), len: 206 aa. Probable hisH, amidotransferase. Similar to many e.g. HIS5_STRCO|P16249 from Streptomyces coelicolor (222 aa), FASTA results: opt: 872, E():0, (61.0% identity in 210 aa overlap). Contains glutamine amidotransferases class-I active site (PS00442). Belongs to the HisH family.

Functional categoryintermediary metabolism and respiration

ProteomicsIdentified 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).
Mutationessential gene by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). 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
