    摘要: Biochemical properties of thylakoid membrane inorganic pyrophosphatase (PPase) from spinach were investigated in this study. Mg2+ (5 mM) markedly stimulated the PPase activity under alkaline pH values. The native substrate for the hydrolytic reaction Of PPase appeared to be magnesiumpyrophosphate. Among anions investigated, only did F� cause severe inhibition. Illumination had no effect on PPase activity, indicating its independence of photosynthetic electron tramsport and associated energization reactions. The radiation inactivation analysis showed that the functional size of PPase was 86.9 � 4.3 kDa. Group specific modification of enzyme demonstrated the presence of essential sulfhydryl residue at the active site which was embedded in the membrane of thylakoid.
