WebJul 19, 2016 · Map-based cloning identified CsChlI as the candidate gene for this mutation which encoded the CHLI subunit of cucumber Mg-chelatase. The 1757-bp CsChlI gene had three exons and a single nucleotide change (G to A) in its third exon resulted in an amino acid substitution (G269R) and the golden leaf color in C528. Web2.1 Overview of magnesium chelatase structure and activity. Magnesium chelatase requires a minimum of three protein subunits for activity and requires ATP hydrolysis and the …

WebNov 24, 2010 · The chlorophyll-deficient gun5-1 and cch Arabidopsis mutants carry single point mutations in the CHLH subunit of the magnesium chelatase enzyme, which catalyses the first committed step of chlorophyll biosynthesis. Recombinant Synechocystis ChlH subunits carrying the gun5-1 or cch mutations are inactive in Mg-chelatase assays, … WebThe chloroplast thioredoxins (TRXs) function as messengers of redox signals from ferredoxin to target enzymes. In this work, we studied the regulatory impact of pea (Pisum sativum) TRX-F on the magnesium (Mg) chelatase CHLI subunit and the enzymatic activation of Mg chelatase in vitro and in vivo.
