High temperature (363K) crystal structure of 5'-Deoxy-5'-methylthioadenosine phosphorylase from Aeropyrum pernix after 30 minutes reaction with substrate
| ||||||||||||
Structural highlights
FunctionMTAP_AERPE Catalyzes the reversible phosphorylation of S-methyl-5'-thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate. Involved in the breakdown of MTA, a major by-product of polyamine biosynthesis. Responsible for the first step in the methionine salvage pathway after MTA has been generated from S-adenosylmethionine. Has broad substrate specificity with 6-aminopurine nucleosides as preferred substrates.[HAMAP-Rule:MF_01963] Contents | ||||||||||||||||||||
