Abstract

Mannosyltransferases in plasma membranes of Dictyostelium discoideum synthesize polyisoprenylphosphomannosides from exogenous polyisoprenylphosphates and GDP-mannose. The specificity of the enzymes depends on the chain length and the saturation of the polyisoprenols. Maximum activity is reached by a alpha-saturated C-55 polyisoprenylphosphate.

摘要

盘基网柄菌质膜中的甘露糖基转移酶可利用外源性多聚异戊二烯磷酸酯和GDP-甘露糖合成多聚异戊二烯磷酸甘露糖苷。这些酶的特异性取决于多聚异戊二烯醇的链长和饱和度。α-饱和的C-55多聚异戊二烯磷酸酯可达到最大活性。
