Chain A   (BCPA_CHLTE | Q46393)
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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
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:0018298    protein-chromophore linkage    The covalent or noncovalent attachment of a chromophore to a protein.
