5'-deoxy-5'-methylthioadenosine phosphorylase

Revision as of 15:08, 11 November 2014 by Michal Harel (talk | contribs)


Function

5’-deoxy-5’-methylthioadenosine phosphorylase (MTAP) catalyzes the reversible phosphorolysis of 5’-deoxy-5’-methylthioadenosine (MTA) to adenine and 5-methylthio-D-ribose-1-phosphate. This reaction is the principle source of adenine in human cells.

Disease

Relevance

MTAP is a potential target of chemotherapy. More than 20% of human various cancer cells do not show MTAP activity.
