phycocyaninn.

Brit.

/ˌfʌɪkə(ʊ)ˈsʌɪənɪn/, U.S.

/ˌfaɪkəˈsaɪənən/

Forms: 1800s phycocyanine, 1800s– phycocyanin.

Origin: A borrowing from Greek, combined with English elements; modelled on a German lexical item. Etymons: phyco- comb. form, Greek κύανος , -in suffix¹.

Etymology: < phyco- comb. form + ancient Greek κύανος a dark-blue mineral (see cyano- comb. form) + -in suffix¹, after German Phycocyan phycocyan n. Compare earlier phycocyan n.

Biochemistry.

Any of various blue or blue-green phycobiliprotein pigments that are the dominant photosynthetic pigments in most blue-green algae and also occur in red algae.

1875 A. W. Bennett & W. T. T. Dyer tr. J. von Sachs Text-bk. Bot. 216 The phycocyanine [Ger. Phycocyan] is diffused from dead or ruptured cells, and thus produces, for example, the blue stains on the paper round herbarium specimens of Oscillatoriæ.

1895 Bot. Gaz. 20 512 Molisch recently showed that the phycoerythrin of the Florideæ is a crystallizable proteid substance, and..he demonstrates the same for phycocyanin.

1934 C. C. Steele Introd. Plant Biochem. v. xv. 152 Chromoproteins..have not been found among the higher plants, although phycocyanin in the Cyanophyceæ and phycoerythrin in the Rhodophyceæ appear to belong to this group.

1999 New Phytologist 144 14/1 During periods of N₂ starvation in Anabaena spp., phycocyanin is degraded by a specific protease..and phycocyanin gene expression is switched off.
