6.6.1.1	ATP	required for activation and chelation steps	644254	
6.6.1.1	GENOMES UNCOUPLED 4	GUN4 enhances measureable Mg-protoporphyrin IX in chloroplast extracts	709047	
6.6.1.1	Gun4	addition of Gun4 up to 0.0005 mM stimulates the wild type enzyme 2-3fold. Up to 0.001 mM Gun4 resurrects the inactive gun5 and cch mutant Mg-chelatase reactions to the level seen in the wild type with no Gun4 present, particularly in the case of mutant gun5	715033
