Adenosine kinase and ribokinase – the RK family of proteins

Abstract.Ribokinase (RK) and adenosine kinase (AK) catalyze the phosphorylation of ribose and adenosine to ribose-5-phosphate and AMP, respectively. Belonging to the RK family of proteins, these enzymes share a number of unique structural and functional elements. Extensive work has been carried out on many aspects of these enzymes in recent years, and we summarize the wealth of information currently available on them. The topics covered include …
