sensitisation complexes as simple artificial models for photosystem II in green. plants. An intrinsic 22 kDa protein of photosystem II has been shown to possess high sequence homology with the CAB gene products, but differs from these proteins by [2]. Y.

First step of Photosystem II. Chlorophyll absorbs light energy. Second step of Photosystem II. Electrons are excited and jump up Photosystem I or PS I contains chlorophyll A-670, chlorophyll A-680, chlorophyll A-695, chlorophyll A-700, chlorophyll B, and carotenoids in the ratio of 20-30 :1, whereas in Photosystem II or PS 2 contains chlorophyll A-660, chlorophyll A-670, chlorophyll A-680, chlorophyll A-695, chlorophyll A-700, chlorophyll B, xanthophylls and phycobilins in the ratio of 3-7 :1. Light energy (indicated by wavy arrows) absorbed by photosystem II causes the formation of high-energy electrons, which are transferred along a series of acceptor molecules in an electron transport chain to photosystem I. Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. 2017-04-20 Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature.

1. Photosystem II (PS II) is involved only in non-cyclic photophosphorylation. 2. Photosystem II (PS II) donates electrons to photosystem I where NADP+ is reduced.

A recent report (Nanba O, Satoh K: Proc. Natl. Acad. Sci. USA 84: 109–112, 1987) described the isolation from spinach of a putative photosystem 2 reaction centre which contained cytochrome b-559 and three other electrophoretically resolvable polypeptide bands, two of which have molecular weights comparable to the D1 and D2 polypeptides.

PSBY-1 and -2 are manganese-binding polypeptides with L-arginine metabolizing enzyme activity. They are a component of the core of photosystem II. They have also a minor catalase-like activity since they cause evolution of oxygen from hydrogen peroxide in a reaction stimulated by manganese. 2019-06-26 1996-09-29 One of the components of the core complex of photosystem II (PSII), required for its stability and/or assembly. PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation.

Photosystem I includes the following pigments: Chlorophyll b, Chlorophyll -a 670, Chlorophyll -a 680, Chlorophyll -a 695, Chlorophyll -a 700 or P700, Carotenoids. 1996-09-29 · Photosystem II, photosystem I, and the components of the photosynthetic electron transport chain are intrinsic proteins of the thylakoid membranes of the chloroplast. A schematic diagram of the important enzymes of the thylakoid membranes, showing the path of electrons and protons during the light reactions is shown to the right. A recent report (Nanba O, Satoh K: Proc. Natl. Acad. Sci.
