Chain H (RCEH_RHOSH | P0C0Y7)

molecular function
	GO:0042314	bacteriochlorophyll binding	Interacting selectively and non-covalently with bacteriochlorophyll, a form of chlorophyll found in photosynthetic bacteria, such as the purple and green bacteria. There are several types, designated a to g. Bacteriochlorophyll a and bacteriochlorophyll b are structurally similar to the chlorophyll a and chlorophyll b found in plants.
	GO:0016168	chlorophyll binding	Interacting selectively and non-covalently with chlorophyll; any compound of magnesium complexed in a porphyrin (tetrapyrrole) ring and which functions as a photosynthetic pigment.
	GO:0045156	electron transporter, transferring electrons within the cyclic electron transport pathway of photosynthesis activity	Enables the directed movement of electrons within the cyclic electron transport pathway of photosynthesis.
biological process
	GO:0055114	oxidation-reduction process	A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
	GO:0015979	photosynthesis	The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide (CO2) using energy obtained from light rather than from the oxidation of chemical compounds.
	GO:0019684	photosynthesis, light reaction	The light reactions of photosynthesis, which take place in photosystems II and I. Light energy is harvested and used to power the transfer of electrons among a series of electron donors and acceptors. The final electron acceptor is NADP+, which is reduced to NADPH. NADPH generated from light reactions is used in sugar synthesis in dark reactions. Light reactions also generate a proton motive force across the thylakoid membrane, and the proton gradient is used to synthesize ATP. There are two chemical reactions involved in the light reactions: water oxidation in photosystem II, and NADP reduction in photosystem I.
	GO:0018298	protein-chromophore linkage	The covalent or noncovalent attachment of a chromophore to a protein.
cellular component
	GO:0016021	integral component of membrane	The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0030077	plasma membrane light-harvesting complex	A plasma membrane protein-pigment complex that may be closely or peripherally associated to photosynthetic reaction centers that participate in harvesting and transferring radiant energy to the reaction center. Examples of this complex are found in bacterial species.
	GO:0042717	plasma membrane-derived chromatophore membrane	The lipid bilayer associated with a plasma membrane-derived chromatophore; surrounds chromatophores that form complete vesicles.

There are two chemical reactions involved in the light reactions: water oxidation in photosystem II, and NADP reduction in photosystem I.
	GO:0009772	photosynthetic electron transport in photosystem II	A photosynthetic electron transport chain in which electrons move from the primary electron acceptor (Quinone, Q) through a chain of electron transport molecules in the thylakoid membrane until they reach the ultimate electron acceptor of Photosystem II, which is plastocyanin (PC). The electron is then passed to the P700 chlorophyll a molecules of the reaction centre of photosystem I.
