Effect of cyclodextrin on improvement of enantioselectivity in the reduction of ketopantolactone with baker's yeast.
Bioorg. Med. Chem. 2(6) , 433-7, (1994) Addition of beta-cyclodextrin improves enantioselectivity dramatically in the reduction of ketopantolactone mediated by baker's yeast. It has been found that the selectivity increases with the decrease in concentration of ketopantolactone in bulk solvent, and... |

Gene cloning and overexpression of two conjugated polyketone reductases, novel aldo-keto reductase family enzymes, of Candida parapsilosis.
Appl. Microbiol. Biotechnol. 64(3) , 359-66, (2004) The genes encoding two conjugated polyketone reductases (CPR-C1, CPR-C2) of Candida parapsilosis IFO 0708 were cloned and sequenced. The genes encoded a total of 304 and 307 amino acid residues for CPR-C1 and CPR-C2, respectively. The deduced amino acid seque... |

LplR, a repressor belonging to the TetR family, regulates expression of the L-pantoyl lactone dehydrogenase gene in Rhodococcus erythropolis.
Appl. Environ. Microbiol. 78(22) , 7923-30, (2012) The L-pantoyl lactone (L-PL) dehydrogenase (LPLDH) gene (lpldh) has been cloned from Rhodococcus erythropolis AKU2103, and addition of 1,2-propanediol (1,2-PD) was shown to be required for lpldh expression in this strain. In this study, based on an exploratio... |

Interaction between ketopantolactone and chirally modified Pt investigated by attenuated total reflection IR concentration modulation spectroscopy.
J. Am. Chem. Soc. 125(44) , 13342-3, (2003) The combination of ATR-IR and modulation spectroscopy allowed for the study of the interaction of ketopantolactone with Pt/Al2O3 films chirally modified by cinchonidine under hydrogenation conditions. The spectra reveal a significant influence of ketopantolac... |

A novel fungal enzyme, NADPH-dependent carbonyl reductase, showing high specificity to conjugated polyketones. Purification and characterization.
Eur. J. Biochem. 174(1) , 37-44, (1988) A novel enzyme which specifically catalyzes the reduction of conjugated polyketones was purified to homogeneity from cells of Mucor ambiguus AKU 3006. The enzyme has a strict requirement for NADPH and irreversibly reduces a number of quinones such as p-benzoq... |
