Cloning and characterization of the thiD/J gene of Escherichia coli encoding a thiamin-synthesizing bifunctional enzyme, hydroxymethylpyrimidine kinase/phosphomethylpyrimidine kinase.
Mizote T., Tsuda M., Smith D.D.S., Nakayama H., Nakazawa T.
A 1.7 kb DNA fragment isolated from an E. coli genomic library was able to complement the thiamin requirement of strains carrying the thiM, thiJ and thiD mutations. The three genes encode hydroxyethylthiazole kinase, hydroxymethylpyrimidine (HMP) kinase and phosphomethylpyrimidine (HMP-p) kinase, ... >> More
A 1.7 kb DNA fragment isolated from an E. coli genomic library was able to complement the thiamin requirement of strains carrying the thiM, thiJ and thiD mutations. The three genes encode hydroxyethylthiazole kinase, hydroxymethylpyrimidine (HMP) kinase and phosphomethylpyrimidine (HMP-p) kinase, respectively. Sequence analysis revealed that the 1.7 kb fragment contained two ORFs of 708 bp and 801 bp. The former ORF complemented the thiM mutation and the latter ORF both the thiJ and thiD mutations. The latter ORF was cloned into the expression vector pET3a, and the encoded protein was purified through three successive column chromatographies. The purified protein was able to convert HMP to its monophosphate and the monophosphate to its pyrophosphate. These results suggest that the two distinct enzyme activities, HMP kinase and HMP-P kinase, are indeed a bifunctional enzyme encoded by a single gene, designated thiDIJ. << Less

Characterization of two kinases involved in thiamine pyrophosphate and pyridoxal phosphate biosynthesis in Bacillus subtilis: 4-amino-5-hydroxymethyl-2-methylpyrimidine kinase and pyridoxal kinase.
Park J.-H., Burns K., Kinsland C., Begley T.P.
Two Bacillus subtilis genes encoding two proteins (currently annotated ThiD and YjbV) were overexpressed and characterized. YjbV has 4-amino-5-hydroxymethyl-2-methylpyrimidine and 4-amino-5-hydroxymethyl-2-methylpyrimidine pyrophosphate kinase activity and should be reannotated ThiD, and B. subtil ... >> More
