Mg-Chelatase Plasmid

Sequence and Features

Overview

This composite part is made up of various genes that form the first part of the chlorophyll biosynthesis pathway. The plasmid contains six genes. They are in the order of ChlI1, ChlD, Gun4, ChlI2, CTH1, followed by ChlH. At the beginning of each gene, a ribosome binding site can be found. Before the ChlH gene, a Plac is located. One can also be found at the beginning of the plasmid. The genes encode for Magnesium chelatase subunit H (ChlH), Magnesium chelatase subunit I (Chli1/Chli2), Magnesium chelatase subunit D (ChlD), Genomes uncoupled 4 (GUN4) and Copper target 1 protein (Cth1). These genes are involved in converting protoporphyrin IX to divinyl protochlorophyllide in the presence of NADPH and O2.

Biology & Literature

ChlI1 and ChlI2 forms a Mg-chelatase complex which catalyzes the insertion of magnesium ion into protoporphyrin IX to yield Mg-protoporphyrin IX. ChID forms an ATP dependent complex with ChlI1 and ChlI2 before acting of protoporphyrin. GUN4 is a tetrapyrrole-binding protein which controls the production of Mg-protoporphyrin IX found only in aerobic photsynthetic organisms. It is thought to participate in plastid-to-nucleus signalling by regulating Mg-protoporphyrin IX synthesis. Finally, ChlH is a chloroplast precursor which plays a role in the regulation of light in chlorophyll biosynthesis.

CTH1 is a functional protein that is developed in the prescense of oxygen or copper. It catalyzes Mg-protoporphyrin IX monomethyl, which converts to divinyl protochlorophyllide in the presence of NADPH and O2.

This biobrick contains six genes from the chlorophyll biosynthetic pathway of Chlamydomonas reinhardtii. These genes are Magnesium chelatase subunit H (ChlH), Magnesium chelatase subunit I (Chli1/Chli2), Magnesium chelatase subunit D (ChlD), Genomes uncoupled 4 (GUN4) and Copper target 1 protein (Cth1). These genes are involved in converting protoporphyrin IX to divinyl protochlorophyllide in the presence of NADPH and O2.
