[ccp4bb] Difference in the substrate specificity for TMP and CMP

2015-05-28 Thread Faisal Tarique
Hello everyone I am working on a 5'-nucleotidase (Mg as a cofactor) and have a decent structure of the same at 2A resolution..While doing its biochemical characterization i found it hydrolyzing TMP: Thymine-5'-monophosphate at much higher rate than CMP Cytosine-5'-monophosphate (40 fold

Hi Faisal, Lots of enzymes aren't too picky when it comes to nucleotide cofactors - depending on their physiological role, they may or may not select for high specificity. I'd encourage you to think about the opposite question - why are some enzymes highly specific for particular nucleosides?
