    Abstract: PURPOSE: A carbonyl reductase of Kluyveromyces marxianus and an isolation and purification method thereof are provided, thereby higher stereo-selectively, cheaply and rapidly carrying out the reduction process. CONSTITUTION: A carbonyl reductase isolated and purified from Kluyveromyces marxianus has the properties of the size of 40 to 42 kDa, the active temperature of 25 to 35 deg. C, and the active pH of 6.5 to 7.5, wherein the carbonyl reductase contains the amino acid sequence of Thr-Phe-Thr-Val-Val-Thr-Gly in the amino-terminal. A method for isolating and purifying the carbonyl reductase of Kluyveromyces marxianus comprises the steps of: (1) culturing Kluyveromyces marxianus; (2) centrifuging the cultured medium to collect the pellet and pulverizing the pellet; and (3) centrifuging the pulverized cell extract to collect the supernatant, and subjecting the supernatant to column chromatography to isolate an active fraction containing active material to substrate, wherein the column uses Q sepharose, phenyl sepharose, high-trap blue and gel filtration chromatography, sequentially.

    Abstract: PURPOSE: Carbonyl compounds and a preparation process thereof using carbonyl reductase isolated from Kluyveromyces marxianus are provided. The carbonyl compounds are useful as intermediates for preparing beta-lactam family antimicrobial agents. CONSTITUTION: Carbonyl compounds represented by the formula(Ia) and (Ib) are provided, wherein R is methyl, ethyl, propyl, isopropyl, isobutyl and allyl containing saturated or unsaturated alkyl, or phenyl containing aryl; R1, R2, R3 and R4 are independently selected from the group consisting of hydrogen, halogen atoms including Br, Cl, F and I, methyl and ethyl containing C1-C4 alkyl, hydroxy, C1-C4 alkoxy, acetoxy containing ester, and phenyl. A process for preparing the carbonyl compound of the formula(Ia) and (Ib) comprises the steps of: mixing a compound of formula(VI) with β-NADPH and a pH 5.0 to 8.0 buffer solution; adding carbonyl reductase isolated from Kluyveromyces marxianus into the mixture; and reacting the mixture at 20 to 40 deg. C for 5 hours to 5 days.
