Biocatalyst with excellent enantioselectivity
Lyophilized powder, Immobilized powder
Lipases (EC 188.8.131.52) are ubiquitous enzymes that catalyze the hydrolysis of fats and oils, playing important roles in pharmaceutical. The lipase from Serratia marcescens (SML) is well-known for its excellent enantioselectivity in biocatalytic hydrolysis of trans-3-(4-methoxyphynyl) glycidic acid methyl ester [(±)-MPGM] to produce (2R, 3S)-3-(4-methoxyphenyl) glycidic acid methyl ester [(-)-MPGM], a key intermediate for the synthesis of diltiazem hydrochloride.
1)Hydrolyze trans-3-(4-methoxyphynyl) glycidicacid methyl ester [(±)-MPGM] to produce (2R, 3S)-3-(4-methoxyphenyl) glycidic acid methyl ester [(-)-MPGM].
2)Hydrolyze (±)-naproxen methyl ester to produce(-)-naproxen.
3)Hydrolyze Fatty acid esters.
4)Catalyze turn ester reaction.
Thermal-stability Be stable below 40°C, unstable at higher than 50°C.
Stability against organic solvents Higher activity In 10%-50% DMSO, isopropyl ether, petroleum ether
In 10%-25% ethanol, acetone and isopropanol,
In 90% isopropyl ether, petroleum ether
50% activity In 50% acetone and isopropanol.
Selectivity to different fatty-acids derives Priory to long-chain (> 10) fatty acids derives.
