abstract：:Two active lysine transport systems were detected in Saccharomycopsis lipolytica. No excretion of lysine out of the cells could be obtained, even by chasing with L-lysine or by poisoning with sodium azide. The kinetic properties of one of the permeases, the high-affinity lysine permease, were studied in detail. Its Km...
