FunFam 4309: Purine or other phosphorylase family 1

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
S-methyl-5'-thioadenosine phosphorylase. [EC: 2.4.2.28]
S-methyl-5'-thioadenosine + phosphate = adenine + S-methyl-5-thio-alpha- D-ribose 1-phosphate.
  • Also acts on 5'-deoxyadenosine and other analogs having 5'-deoxy groups.
 4 C3MMI7 C3NBW4 C3NN50 D2PHT4
Purine-nucleoside phosphorylase. [EC: 2.4.2.1]
(1) Purine nucleoside + phosphate = purine + alpha-D-ribose 1-phosphate. (2) Purine deoxynucleoside + phosphate = purine + 2'-deoxy-alpha-D-ribose 1-phosphate.
  • Specificity not completely determined.
  • Can also catalyze ribosyltransferase reactions of the type catalyzed by EC 2.4.2.5.
