Microbial Reduction of Ketopantoyl Lactone to Pantoyl Lactone [PDF]
Applied Microbiology, 1974 The results of a microbial survey study have shown that the ability to reduce added ketopantoic acid (or ketopantoyl lactone) and accumulate pantoic acid (or pantoyl lactone) in the growth medium is widespread among diverse fungi. The reductions generally proceeded with less than full stereoselectivity. However, specific strains of

The development of human sera tests for HDL-bound serum PON1 and its lipolactonase activitys⃞
Journal of Lipid Research, 2007 Serum paraoxonase (PON1) is a lipolactonase that associates with HDL-apolipoprotein A-I (HDL-apoA-I) and thereby plays a role in the prevention of atherosclerosis. Current sera tests make use of promiscuous substrates and provide no indications regarding
