Some characteristics of sulphate uptake into synaptosomes

Abstract:
Incorporation of Na235SO4 by ovine brain Ficoll-prepared synaptosomes were studied as a function of time, temperature and substrate concentration. The rate of uptake obeyed Michaelis-Menten kinetics and apparent Km value of 4.4 mM Na2SO4 was determined. In the presence of p-hydroxymercuribenzoate a reduction in sulphate uptake was noted which suggests that thiol groups may possibly be implicated in the uptake mechanism.
