TypeCDS
FunctionInvolved in signal transduction (via phosphorylation). Thought to be involved in membrane transport. Phosphorylates the peptide substrate myelin basic protein (MBP) at serine and threonine residues [catalytic activity: ATP + a protein = ADP + a phosphoprotein].
ProductAnchored-membrane serine/threonine-protein kinase PknF (protein kinase F) (STPK F)
CommentsRv1746, (MTCY28.09, MTCY04C12.30), len: 476 aa. pknF, transmembrane serine/threonine-protein kinase (see citations below), highly similar to KY28_MYCTU|Q10697 probable serine/threonine-protein kinase from Mycobacterium tuberculosis (589 aa), FASTA scores: opt: 870, E(): 0, (41.6% identity in 406 aa overlap). Contains PS00108 Serine/Threonine protein kinases active-site signature. Contains Hank's kinase subdomain. Belongs to the Ser/Thr family of protein kinases. Experimental studies show evidence of auto-phosphorylation. Start site chosen by homology, may extend further upstream.
Functional categoryRegulatory proteins
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate and membrane protein fraction of M. tuberculosis H37Rv but not whole cell lysates (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
