chromoplast

A plastid containing pigments other than chlorophyll, usually yellow and orange carotenoid pigments.

xanthophyll binding

Binding to xanthophylls, any of several neutral yellow to orange carotenoid pigments containing oxygen.

trimethylamine monooxygenase activity

Catalysis of the reaction: N,N,N-trimethylamine + NADPH + H+ + O2 = N,N,N-trimethylamine N-oxide + NADP+ + H2O.

pterinosome

A tissue-specific, membrane-bounded cytoplasmic organelle within which pteridine pigments are synthesized and stored. Pterinosomes are synthesized in xanthophores and erythrophore cells and are yellow, orange or red in appearance.

obsolete ubiquitin-calmodulin ligase activity

OBSOLETE. Catalysis of the reaction: n ATP + calmodulin + n ubiquitin = n AMP + n diphosphate + ubiquitin(n)-calmodulin.

N,N-dimethylaniline monooxygenase activity

Catalysis of the reaction: N,N-dimethylaniline + NADPH + H+ + O2 = N,N-dimethylaniline N-oxide + NADP+ + H2O.

dimethylaniline-N-oxide aldolase activity

Catalysis of the reaction: N,N-dimethylaniline N-oxide = N-methylaniline + formaldehyde.

carotenoid vesicle

A tissue-specific cytoplasmic vesicle surrounded by a membrane half-leaflet within which carotenoid pigments are stored. Carotenoid vesicles are synthesized in xanthophores and erythrophore cells and are yellow, orange or red in appearance.

alpha-glucan, water dikinase activity

Catalysis of the reaction: [(1->4)-alpha-D-glucosyl](n) + n ATP + n H2O = [(1->4)-6-phospho-alpha-D-glucosyl](n) + n AMP + 2n H+ + n phosphate.

trimethyllysine dioxygenase activity

Catalysis of the reaction: 2-oxoglutarate + N(6),N(6),N(6)-trimethyl-L-lysine + O2 = 3-hydroxy-N(6),N(6),N(6)-trimethyl-L-lysine + CO2 + succinate.
