Dictionary » P » Protein kinase Protein kinaseprotein kinase (Science: 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. ![]()

Re: Kinases... in the molecule. If the terminal phosphate of ATP is transferred to a protein (releasing free ADP) then the system is in a lower-energy state that ... drive the reaction to the ADP & phosphoprotein side. Not every kinase will use ATP as a substrate. Other high-energy phosphates are available ...

Molecular gene (genome) concept scientifically untenable... by changes in gene expression, not in DNA. It's clear nowadays, that protein-coding sequences play only minor role in DNA (BTW there are genes, ... in cancer occurence. And more importantly, we do have gene for glukose kinase, for pyruvate dehydrogenase etc.
