Abstract excerpt

Two transport systems for L-arginine were evident in Anabaena sp. strain PCC 7120: a high-affinity one (Km, 1.7 microM) that accumulated arginine within the cells through an energy-requiring process and another one that exhibited low affinity for L-arginine (Km, 0.75 mM) and was unable to accumul...
