Molecular cloning, identification and characterization of 2-methyl-3-hydroxypyridine-5-carboxylic-acid-dioxygenase-coding gene from the nitrogen-fixing symbiotic bacterium Mesorhizobium loti.
The gene (mlr6788) of a nitrogen-fixing symbiotic bacterium Mesorhizobium loti MAFF303099 has been identified as a gene coding for 2-methyl-3-hydroxypyridine-5-carboxylic acid dioxygenase (MHPCO),Expand

The nitrogen-fixing symbiotic bacterium Mesorhizobium loti has and expresses the gene encoding pyridoxine 4-oxidase involved in the degradation of vitamin B6.
The gene product of mll6785 of a nitrogen-fixing symbiotic bacterium Mesorhizobium loti MAFF303099 was identified as pyridoxine 4-oxidase, the first enzyme in the vitamin B6-degradation pathway. TheExpand

Inhibition of diphenolase activity of tyrosinase by vitamin b(6) compounds.
The vitamin B(6) compounds pyridoxine (PN), pyridoxamine (PM), pyridoxal (PL), and pyridoxamine 5'-phosphate (PMP) inhibited the diphenolase activity of mushroom tyrosinase. PM showed the highestExpand

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

Identification of a new tetrameric pyridoxal 4-dehydrogenase as the second enzyme in the degradation pathway for pyridoxine in a nitrogen-fixing symbiotic bacterium, Mesorhizobium loti.
We have found for the first time that a chromosomal gene, mlr6807, in Mesorhizobium loti encodes a new tetrameric pyridoxal 4-dehydrogenase (PLDH). The recombinant enzyme expressed in EscherichiaExpand

Coenzyme precursor-assisted cooperative overexpression of an active pyridoxine 4-oxidase from Microbacterium luteolum.
The overexpression system of the active pyridoxine 4-oxidase from Microbacterium luteolum was developed. When chaperonin GroEL/ES genes in plasmid pKY206 were coexpressed, the pyridoxine 4-oxidaseExpand
