Stable vitamin B6 derivative

A protein, which is an aminoketone asymmetric reductase, having an effect of producing d-pseudoephedrine by acting on 1-2-methylaminopropiophenone, and having the following physiochemical properties:

Aminoketone asymmetric reductase and nucleic acid thereof

Process for the production of optically active &bgr;-amino alcohols

A novel enzyme which is useful in the optical resolution of D,L-pantolactone via D-selective asymmetric hydrolysis and a gene encoding the the same are provided. The invention discloses the gene coding for a natural D-pantolactone hydrolase (for example, one originating in ) or proteins having an activity substantially equivalent thereto; host cells transformed with DNA containing a nucleotide sequence coding for said protein, processes for producing said protein via using said host cells and uses of said proteins and host cells.
