General annotation
FunctionThreonine biosynthesis from asparate (fourth step) [catalytic activity: ATP + L-homoserine = ADP + O-phospho-L-homoserine].
ProductProbable homoserine kinase ThrB
CommentsRv1296, (MTCY373.16), len: 316 aa. Probable thrB, homoserine kinase (see citation below), highly similar to KHSE_MYCLE|P45836 from Mycobacterium leprae (314 aa), FASTA scores, opt: 1657, E(): 0, (82.0% identity in 311 aa overlap). Contains PS00639 Eukaryotic thiol (cysteine) proteases histidine active site, and PS00627 GHMP kinases putative ATP-binding domain.
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).
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).
