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 decreas...

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 CP...

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 expre...
