(deoxy)nucleoside-phosphate kinase  M-CSA #637

The deoxynucleotide kinase from phage T4 is able to catalyse the phosphorylation of GMP, methyl-CMP and TMP to the corresponding nucleotide diphosphate using ATP as the phosphate donor. This process is of particular interest because of the diverse specificity of the enzyme: most species deoxynucleotide kinases are only able to phosphorylate one dNMP, but owing to the selective pressure on the phage to have as small a genome as possible to allow easier infection of the bacteria, a wider specificity has developed. The sequence of the enzyme displays no homology to any other kinases, but does include the triphosphate binding consensus sequence.
