A, B	PF09150	Orange carotenoid protein, N-terminal (Carot_N)	Orange carotenoid protein, N-terminal	Members of this family adopt an alpha-helical structure consisting of two four-helix bundles. They are predominantly found in prokaryotic orange carotenoid protein, and carotenoid binding proteins [1].	Domain
