Summary:
Phosphorylation of hydroxymethylpyrimidine (HMP) by HMP kinase is the first step in a non-essential salvage reaction of the superpathway of thiamin diphosphate biosynthesis I pathway. This pathway is common to both E.coli and S. typhimurium and has been extensively studied in both organisms. Salvage of HMP from the culture medium has been experimentally demonstrated in S. typhimurium [Bellion83].
