Photosynthesis by Isolated Pea Chloroplasts

Some Effects of Adenylates and Inorganic Pyrophosphate 1

Zivko S. Stankovic2 and David A. Walker

a Department of Botany, The University of Sheffield, Sheffield S10 2TN England

When added singly to chloroplasts isolated from young pea (Pisum sativum) leaves, both inorganic pyrophosphate (PPi) and small quantities (0.2 mM) of ADP inhibit photosynthesis, but when added together they cause a marked stimulation. ATP (at 0.2 mM) is less inhibitory (or not inhibitory) when added alone, but like ADP, stimulates when added in the presence of PPi. This behavior is in marked contrast to that of spinach (Spinacia oleracea) chloroplasts which are normally stimulated rather than inhibited by PPi and which are largely unresponsive to exogenous adenylates. The inhibitory behavior of PPi with pea chloroplasts was observed under conditions where external hydrolysis to Pi is negligible. It is proposed that the exchange of organic and PPi across the chloroplast envelope may be more rapid in chloroplasts from young pea leaves than in chloroplasts from spinach and that interaction between these two processes could account for the principal observations.
