| Comment | This model represents a small clade of purine nucleotide phosphorylases found in certain gamma proteobacteria. The gene is part of an operon for the degradation of xanthosine and is
induced by xanthosine [1]. The enzyme is also capable of acting on inosine and guanosine (but not adenosine) in a manner similar to those other phosphorylases to which it is closely related
(TIGR01698, TIGR01700). |
