The differential metabolite profiles of acute lymphoblastic leukaemic patients treated with 6-mercaptopurine using untargeted metabolomics approach.

Z Bannur et al.

Clinical biochemistry, 47(6), 427-431 (2014-03-04)

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

Molecular cloning, expression, and properties of an unusual aldo-keto reductase family enzyme, pyridoxal 4-dehydrogenase, that catalyzes irreversible oxidation of pyridoxal.

Nana Yokochi et al.

The Journal of biological chemistry, 279(36), 37377-37384 (2004-07-01)

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 from a symbiotic nitrogen-fixing bacterium Mesorhizobium loti: cloning, expression, and characterization.

Junichi Funami et al.

Biochimica et biophysica acta, 1753(2), 234-239 (2005-10-18)

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
