摘要
Urea-induced aggregation of chicken liver fatty acid synthase [acyl-Coa:malonyl-CoA C-acyltransferase (decarboxylating, oxoacyl-and enoyl-reducing and thioester-hydrolyzing), EC 2.3.1.85] was studied. The aggregation was facilitated at increased ionic strength. Methyl-beta-cyclodextrin and some osmolytes, such as glycerol, sucrose, proline, glycine, and heparin, could effectively prevent the aggregation, implying an artificial chaperone role of those substances during fatty acid synthase unfolding. The osmolytes also protected the enzyme from inactivation.
