Acute lymphoblastic leukaemia (ALL) has posed challenges to the clinician due to variable patients' responses and late diagnosis. With the advance in metabolomics, early detection and personalised treatment are possible. Metabolomic profile of 21 ALL patients treated with 6-mercaptopurine and

Microbacterium luteolum YK-1 has pyridoxine degradation pathway I. We have cloned the structural gene for the second step enzyme, pyridoxal 4-dehydrogenase. The gene consists of 1,026-bp nucleotides and encodes 342 amino acids. The enzyme was overexpressed under cold shock conditions

4-Pyridoxolactonase is involved in the degradation pathway for pyridoxine, a free form of vitamin B6. The gene (mlr6805) encoding the putative 4-pyridoxolactonase of nitrogen fixing symbiotic microorganism Mesorhizobium loti MAFF303099 has been identified based on the genome database. The gene

A determination method for individual natural vitamin B(6) compounds was developed. The vitamin B(6) compounds were specifically converted into 4-pyridoxolactone (PAL), a highly fluorescent compound, through a combination of enzymatic reactions and HCl-hydrolysis. PAL was then determined by HPLC. Pyridoxal

The effects of increased intake of pyridoxine hydrochloride on plasma vitamin B6 metabolism within therapeutic limits (up to 800 mg/day) were investigated. Maximum plasma concentrations of pyridoxal phosphate were attained at relatively low intakes of pyridoxine hydrochloride. Two metabolism thought
