General annotation
| Type | CDS |
| Function | Involved in signal transduction (via phosphorylation). Involved in transcriptional regulatory mechanism and in the regulation of secondary metabolites [catalytic activity: ATP + a protein = ADP + a phosphoprotein]. |
| Product | Serine/threonine-protein kinase transcriptional regulatory protein PknK (protein kinase K) (STPK K) |
| Comments | Rv3080c, (MTV013.01c-MTCY22D7.01), len: 1110 aa. pknK, serine/threonine protein kinase involved in transcriptional regulatory function (see citation below). Similar but shorter in N-terminus (approximately 300 residues) to others e.g. Q48411|ACOK transcriptional regulatory protein of aco ABCD operon from Klebsiella pneumoniae (921 aa), FASTA scores: opt: 886, E(): 7.6e-37, (27.75% identity in 829 aa overlap); Q9HX92|PA3921 probable transcriptional regulator from Pseudomonas aeruginosa (belongs to the LuxR/UhpA family of transcriptional regulators) (906 aa), FASTA scores: opt: 760, E(): 1.5e-30, (29.55% identity in 822 aa overlap); Q9I2X9|PA1760 probable transcriptional regulator from Pseudomonas aeruginosa (belongs to the LuxR/UhpA family of transcriptional regulators) (907 aa), FASTA scores: opt: 696, E(): 2.3e-27, (25.85% identity in 685 aa overlap); P06993|malt (alias BAB37683|ECS4260 and AAG58520|malt) positive regulator of MAL regulon from Escherichia coli strain O157:H7 (901 aa), FASTA scores: opt: 660, E(): 1.4e-25, (29.25% identity in 530 aa overlap); Q9KNF3|VCA0011 malt regulatory protein from Vibrio cholerae (belongs to the LuxR/UhpA family of transcriptional regulators) (921 aa), FASTA scores: opt: 626, E(): 7.2e-24, (25.8% identity in 659 aa overlap); etc. N-terminal region similar to N-terminus of serine/threonine kinases e.g. Q9KK90|PKMA serine/threonine kinase (similar to the Ser/Thr family of protein kinases) from Amycolatopsis mediterranei (589 aa), FASTA scores: opt: 545, E(): 5.7e-20, (34.45% identity in 334 aa overlap); Q9RPT5|AMK serine/threonine protein kinase homolog (similar to the Ser/Thr family of protein kinases) from Amycolatopsis mediterranei (606 aa), FASTA scores: opt: 537, E(): 1.5e-19, (35.55% identity in 346 aa overlap); Q9L0I0|PKAD protein serine/threonine kinase from Streptomyces coelicolor (599 aa), FASTA scores: opt: 520, E(): 1e-18, (36.1% identity in 324 aa overlap); etc. N-terminal part also similar to O53510|PKNL_MYCTU|Rv2176|MT2232|MTV021.09 probable serine/threonine-protein kinase from Mycobacterium tuberculosis strain H37Rv (399 aa), FASTA scores: opt: 511, E(): 2.1e-18, (35.15% identity in 313 aa overlap). Contains PS00107 Protein kinases ATP-binding region signature and PS00017 ATP/GTP-binding site motif A (P-loop). Contains Hank's kinase subdomain. First part of the protein seems belong to the Ser/Thr family of protein kinases, and second parts seems belongs to the LuxR/UhpA family of transcriptional regulators. |
