1 GO annotations of cellular component

Name Definition
chloroplast thylakoid lumen The cavity enclosed within the chloroplast thylakoid membrane. An example of this component is found in Arabidopsis thaliana.

2 GO annotations of molecular function

Name Definition
catechol oxidase activity Catalysis of the reaction: 2 L-dopa + O2 = 2 H2O + 2 L-dopaquinone. This reaction catalyzes exclusively the oxidation of catechols (i.e., o-diphenols) to the corresponding o-quinones.
metal ion binding Binding to a metal ion.

1 GO annotations of biological process

Name Definition
pigment biosynthetic process The chemical reactions and pathways resulting in the formation of a pigment, any general or particular coloring matter in living organisms, e.g. melanin.
