A process for the enzymatic production of vitamin B6 which includes incubating 1-deoxy-D-threo-pentulose and 4-hydroxy-L-threonine with an enzyme system that is cell free or essentially cell free and prepared from the cells of a microorganism belonging to the genus Rhizobium, Sinorhizobium, Flavobacterium, Chryseobacterium, Lactobacillus, Arthrobacter, Bacillus, Klebsiella, Escherichia, Pseudomonas, Stenotrophomonas, Enterobacter, Serratia, Corynebacterium, Brevibacterium, Exiguobacterium, Saccharomyces, Yamadazyma, Pichia or Candida, in the presence of NADP+, NAD+, ATP. Manganese and magnesium ions stimulate the above reaction. This process affords high yields of vitamin B6, a vitamin essential for the nutrition of animals, plants and microorganisms, and which is also useful as a medicine or food additive. In addition, an enzyme reaction system for producing vitamin B6 and a process for making the enzyme reaction system are also provided.
