Protein Name: Magnesium-chelatase subunit ChlI-2, chloroplastic

UniprotKB/SwissProt ID: Q5XF33 (Q5XF33)

Gene Name: CHLI2

Organism: Arabidopsis thaliana (Mouse-ear cress)

Function: Involved in chlorophyll biosynthesis. Catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX. The reaction takes place in two steps, with an ATP-dependent activation followed by an ATP-dependent chelation step. Possesses low affinity for ATP and may play a limited role in chlorophyll biosynthesis, and contributes to the assembly of the Mg-chelatase complex

Protein Subcellular Localization: Plastid, chloroplast
