General annotation
FunctionInvolved in histidine biosynthesis pathway (at the third step) [catalytic activity: 5-phosphoribosyl-AMP + H(2)O = 5-(5-phospho-D-ribosylaminoformimino)-1-(5-phospho-ribosyl) imidazole-4- carboxamide.]
ProductProbable phosphoribosyl-AMP 1,6 cyclohydrolase HisI
CommentsRv1606, (MTV046.04), len: 115 aa. Probable hisI, phosphoribosyl-AMP 1,6 cyclohydrolase, similar to several e.g. X82010|RSHISI_2 HISI from Rhodobacter sphaeroides (119 aa), FASTA scores: opt: 378, E(): 2.8e-21, (52.3% identity in 109 aa overlap); etc.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen 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 (See de Souza et al., 2011).
MutantEssential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
