It is involved in photosynthetic electron transfer in the anoxygenic photosynthetic bacterium. Can donate electrons to cytochrome c-554. It has an intense absorption band near 600 nm in the oxidized form. Contains a type 1 copper(II) ion characterized by an intense blue color. Glycosylation Status Glycosylation Type N(Asn),(Ser/Thr)- linked Technique(s) used for Glycosylation Detection Thymol sulfuric acid-staining Literatures Reference(s) 1) McManus, J.D., Brune, D.C., Han, J., Sanders-Loehr, J., Meyer, T.E., Cusanovich, M.A., Tollin, G. and Blankenship, R.E.
