Protein Variants

Protein Variants Comment Organism
additional information barley mutant albostrains show a severe block in chloroplast development as a result of a mutationally induced lack in plastid ribosomes, phenotype: white leaves due to chlorophyll deficiency, analysis of the tetrapyrrole biosynthetic pathway shows that the mutant has reduced activity of Mg-chelatase, Fe-chelatase, and Mg-protoporphyrin IX methyltransferase, several other enzymes involved in the pathway are deregulated, e.g. the chlorophyll synthetase, carotenoid content in leaves, overview Hordeum vulgare
