soluble chloroplast protease processes the Euglena polyprotein precursor to the light harvesting chlorophyll a/b binding protein of photosystem II
The Euglena light harvesting chlorophyll a/b binding protein of photosystem II (LHCPII) is synthesized as a polyprotein precursor composed of 8 LHCPIIs covalently joined by a decapeptide. A soluble chloroplast protease releases LHCPII from the polyprotein. The polyprotein processing peptidase has a...

Zusammenfassung: | The Euglena light harvesting chlorophyll a/b binding protein of photosystem II (LHCPII) is synthesized as a polyprotein precursor composed of 8 LHCPIIs covalently joined by a decapeptide. A soluble chloroplast protease releases LHCPII from the polyprotein. The polyprotein processing peptidase has a pH optima between 8.0 and 9.0. It is inhibited by Zn2+, Cu2+, phenylmethylsulfonyl fluoride and E64 suggesting it is a novel thiol protease. |
