STN 8

from Wikipedia, the free encyclopedia

STN 8 is an enzyme that, together with STN 7, causes the phosphorylations in thylakoids of chloroplasts in the course of photosynthesis .

properties

STN 8 is a kinase . STN 8 mainly phosphorylates the central proteins of photosystem II . Presumably, this phosphorylation of the central proteins significantly regulates the regeneration of photosystem II and its stability. It is also said to play a role in the development of the thylakoid membrane. The complementary phosphatase to STN8 is PBCP.
