Abstract: Isolated nucleic acid (I) that encodes a polypeptide (II) with L-pantolactone hydrolase activity is (i) a 810 bp sequence (1); (ii) equivalents of (i) within the degeneracy of the genetic code; (iii) derivatives of (1) that encode a polypeptide at least 50% homologous with a 269 amino acid protein (2) and having essentially the same enzymatic activity; and (iv) functional equivalents of (i)-(iii). Independent claims are also included for the following: (a) protein (IIa) encoded by (I); (b) nucleic acid construct (A) containing (A) linked to at least one regulatory sequence; (c) vector containing (I) or (A); (d) microorganisms containing (I), (A) or the vector of (c); and (e) production of D-pantolactone by treating the racemate with an L-pantolactone hydrolase.

Abstract: The invention relates to a method for producing the optically active alkanols of formula (I), wherein n is an integer of from 0 to 5; Cyc represents an optionally substituted, mononuclear or polynuclear, saturated or unsaturated, carbocylic or heterocyclic ring, and R1 represents halogen, SH, OH, NO2, NR2R3 or NR2R3R4+X−, wherein R2, R3 and R4 independently represent H or a lower alkyl or lower alkoxy group and X− represents a counterion. According to the invention, an enzyme (E) selected from the groups of dehydrogenases, aldehyde reductases and carbonyl reductases is incubated in a medium containing the alkanone of formula (II), wherein n, Cyc and R1 are defined as above, in the presence of reduction equivalents. The compound of formula (II) is enzymatically reduced to the compound of formula (I) and the reduction equivalents consumed during reaction are regenerated by reacting a sacrificial alcohol to the corresponding sacrificial ketone using enzyme (E) and at least partially removing the sacrificial ketone from the reaction medium, and then isolating the product (I) so produced.
