|
|
|
|
|
|
||
| UniProt code: P0ABP9. |
|
||
| Organism: | |
Escherichia coli O157:H7. |
| Taxonomy: | |
Bacteria; Proteobacteria; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia. |
|
||
|
||
| Function: | |
Catalyzes the reversible phosphorolytic breakdown of the N- glycosidic bond in the beta-(deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1- phosphate. {ECO:0000255|HAMAP-Rule:MF_01627}. |
|
||
| Catalytic activity: | |
Reaction=a purine D-ribonucleoside + phosphate = a purine nucleobase + alpha-D-ribose 1-phosphate; Xref=Rhea:RHEA:19805, ChEBI:CHEBI:26386, ChEBI:CHEBI:43474, ChEBI:CHEBI:57720, ChEBI:CHEBI:142355; EC=2.4.2.1; Evidence={ECO:0000255|HAMAP-Rule:MF_01627}; |
| Catalytic activity: | |
