General annotation
TypeCDS
FunctionInvolved in isoleucine biosynthesis (first step). Catalyzes the formation of alpha-ketobutyrate from threonine in a two step reaction. The first step is a dehydration of threonine, followed by rehydration and liberation of ammonia [catalytic activity: L-threonine + H(2)O = 2-oxobutanoate + NH(3) + H(2)O].
ProductProbable threonine dehydratase IlvA
CommentsRv1559, (MTCY48.06c), len: 429 aa. Probable ilvA, threonine dehydratase, biosynthetic protein, similar to several e.g. THD1_CORGL|Q04513 threonine dehydratase biosynthetic (436 aa), FASTA scores: opt: 1694, E(): 0, (61.9% identity in 415 aa overlap). Contains PS00165 Serine/threonine dehydratases pyridoxal-phosphate attachment site.
Functional categoryIntermediary metabolism and respiration
ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). 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).
MutantEssential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
