Phosphorylation nucleoside polyphosphate synthesis

These polyphosphates can then phosphorylate nucleosides rather efficiently.48 If amino acids are present then AMP-amino acids are synthesized (see under peptide synthesis), but if imidazole is present then im-... 

Polyphosphate kinase has been found able to phosphorylate nucleoside diphosphates to give nucleoside triphosphates, using PolyP as a phosphate donor. Therefore, the possibility of using PolyP and polyphosphate kinase instead of phosphoenol pyruvate and pyruvate kinase for enzymatic oligosaccharide synthesis was examined, because PolyP is quite cheap when compared with phosphoenol pyruvate (Noguchi and Shiba, 1998 Shiba et al, 2000). Attempts were made to synthesize N-acetyllactosamine (Gal (f> 1-4) GlcNAc) using the nucleoside diphosphate kinase-like activity of polyphosphate kinase, where UDP-Glc pyrophosphorylase and UDP-Glc 4-epimerase catalyse the synthesis of UDP-Glc from...
