产品介绍

产品描述

Isovitexin 2''-O-arabinoside is a natural product from Secale cereale.

体外活性

Km-values for the substrates p-coumaroyl-CoA and caffeoyl-CoA were 0.6 and 1.45 μM, respectively, the corresponding Km-values for malonyl-CoA were 1.4 and 1.5 μM. The pH-optimum for the formation of 2?2,4,4?2,6?2-tetrahydroxychalcone was 8 and for the formation of 2?2,3,4,4?2,6?2-pentahydroxychalcone, 6.5. A 50% reduction in enzyme activity was caused by 9 μM apigenin, 13 μM luteolin, 36 μM CoA, 45 μM naringenin, 45 μM eriodictyol, and 62 μM Isovitexin 2''-O-arabinoside. SDS-PAGE analysis of the purified enzyme revealed two peptides with apparent molecular weights of 43 and 44 kd, respectively.
