physiological function | Arabidopsis thaliana NtrC knockout mutants show lower magnesium protoporphyrin IX and magnesium protoporphyrin IX monomethylester steady-state levels, the substrate and the product of protoporphyrin IX methyltransferase CHLM preceding MgPMME cyclase, while protoporphyrin IX strongly accumulates in mutant leaves after 5-aminolevulinic acid feeding. The mutant has a reduced capacity to synthesize 5-aminolevulinic acid and reduced CHLM activity compared with the wild-type. The contents of glutamyl-transfer RNA reductase1 and CHLM are reduced. NtrC physically interacts with glutamyl-transfer RNA reductase1 and CHLM. NtrC mutant plants contain partly oxidized CHLM, the wild-type has only reduced CHLM | Arabidopsis thaliana |
