Function

Catalyzes the phosphorylation of guanosine and inosine to GMP and IMP, respectively. Can also use deoxyguanosine and xanthosine, but not adenosine, uridine, cytidine or deoxythymidine. Shows a strong preference for guanosine.

Biological Context

Pathway: Purine metabolism; GMP biosynthesis via salvage pathway

Product Specifications

Recombinant Escherichia coli Guanosine-inosine kinase (gsk) is a recombinant protein, expressed in E.coli, covering amino acids 1-434aa, with N-terminal 10xHis-tagged and C-terminal Myc-tagged tag, molecular weight 55.9kDa, purity Greater than 90% as determined by SDS-PAGE..
