| S6 kinase | <enzyme, molecular biology> Widely used abbreviation for phosphokinase, an enzyme catalysing transfer of phosphate from ATP to a second substrate usually specified in less abbreviated name, for example creatine phosphokinase (creatine kinase), protein kinase. Serine / threonine kinases phosphorylate on serine or threonine residues, tyrosine kinases on tyrosines. (18 Nov 1997) |

| protamine kinase | <enzyme> An aspect of protein kinase (ec 2.7.1.37) in which serine residues in protamines and histones are phosphorylated in the presence of ATP. Chemical name: ATP:protamine O-phosphotransferase Registry number: EC 2.7.1.70 (12 Dec 1998) |
| SCH9 protein kinase | <enzyme> Acts independently of camp-dependent protein kinase and the transcriptional activator adr1 in controlling yeast adh2 expression Registry number: EC 2.7.1.- (26 Jun 1999) |
| protein acyl kinase | <enzyme> Transfers gamma-phosphate of ATP to a protein acceptor with formation of an acyl phosphate bond Registry number: EC 2.7.2.- (26 Jun 1999) |
| protein-histidine kinase | <enzyme> Sass involved in transduction of starvation and cell density inputs; hkna isolated from bacillus thuringiensis; ciah isolated from streptococcus pneumoniae; do not confuse with plp1 protein Registry number: EC 2.7.3.- Synonym: histidine protein kinase, histidine kinase, hkna gene product, ciah gene product, kinc gene product, prrb gene product, plec gene product, mxcq gene product, rese gene product, hpka gene product, comd gene product, plpa gene product (phytochrome-like), divj gene product, sensor histidine kinase, sass gene product (26 Jun 1999) |
| protein kinase | <enzyme> Enzyme catalysing transfer of phosphate from ATP to hydroxyl side chains on proteins, causing changes in function. most phosphate on proteins of animal cells is on serine residues, less on threonine, with a very small amount on tyrosine residues. Tyrosine kinases phosphorylate proteins on tyrosine, serine / threonine kinases on serine or threonine. (18 Nov 1997) |
| protein kinase c | <enzyme> An enzyme that phosphorylates proteins on serine or threonine residues in the presence of physiological concentrations of calcium and membrane phospholipids. The additional presence of diacylglycerols markedly increases its sensitivity to both calcium and phospholipids. The sensitivity of the enzyme can also be increased by phorbol esters and it is believed that protein kinase c is the receptor protein of tumour-promoting phorbol esters. Registry number: EC 2.7.1.- (12 Dec 1998) |
| herpes simplex virus type 1 UL13 protein kinase | <enzyme> Phosphorylates icp22 and involved in the accumulation of alpha and gamma mrnas and proteins in the infected cells; aa sequence has been determined Registry number: EC 2.7.1.- Synonym: ul13 protein kinase, hsv-1, hsv-1 ul13 protein, hsv-1 ul13 pk, u(l)13 protein kinase, protein kinase ul13 (26 Jun 1999) |
| protein-proline kinase | <enzyme> Phosphorylates synapsin i; phosphorylation takes place on serine 20, which is flanked by two proline molecules; heterodimer of p34(cdc2)/p58(cyclin a) Registry number: EC 2.7.10.- Synonym: proline-directed protein kinase (26 Jun 1999) |
| protein-tyrosine kinase | <enzyme> An enzyme that catalyses the phosphorylation of tyrosine residues in proteins with ATP or other nucleotides as phosphate donors.12. Chemical name: ATP:protein-tyrosine O-phosphotransferase Registry number: EC 2.7.1.112 (12 Dec 1998) |
