Abstract:
:An extracellular chitinase from Streptomyces halstedii AJ-7, a broad spectrum antifungal biocontrol agent, was characterized and purified. The apparent molecular weight of the purified protein was 55 kDa, Km value and Vmax of the protein for colloidal chitin were 3.2 mg ml(-1) and 118 micromol h(-1), respectively. The growth and chitinase activity of S. halstedii AJ-7 were enhanced by adding of 0.1% killed mycelium of Fusarium oxysporium in a medium containing 0.2% colloidal chitin.

杂志文章abstract::16,17-Epoxysterol plays an important role in pharmaceutical steroid synthesis. To investigate the potential application of cytochrome P450 for epoxysterol synthesis, an approach to the epoxidation of 16,17-epoxysterol, based on directed evolution of cytochrome P450 BM-3, was developed. This comprised random gene mutag...
