Abstract
Soluble extracts of isolated rat liver parenchymal cells contained three proteases with alkaline pH optima. One protease was a high molecular weight (Mr = 500,000) enzyme which was stimulated by ATP. The other two proteases were totally dependent on calcium for activity and displayed different calcium concentration requirements. One was half-maximally activated by 150 μM Ca2+ while the other required only 10 μM Ca2+ for half-maximal activation.
