Polypeptide sequence alignment of 42-kDa subunits of Mg-chelatase. The barley sequence and 5 of the 14 sequences available in the GenBank Database: Hvu (Hordeum vulgare; barley; GenBank accession no. U26545), Gma (Glycine max; soybean; D45857), Nta (N. tabacum; tobacco; AF014053), Ath (Arabidopsis thaliana; thale cress; X91411), Rca (Rhodobacter capsulatus; Z11165), and Rsp [R. sphaeroides; AF017642 (AJ001690)]. The N-terminal sequence of the soybean, tobacco, and thale cress polypeptides is the same as that of the unprocessed proteins. Conserved amino acid residues in all 14 sequences are marked by asterisks. The species of origin of the 42-kDa subunits (not displayed) are Porphyra purpurea (U38804), Odontella sinensis (Z67753), Cryptomonas phi (Z21976), Anabaena variabilis (D49426), Synechocystis PCC6803 (U35144), Olisthodiscus luteus (Z21959), Chlorobium vibrioforme (Z83933), and Heliobacillus mobilis (AF080002). Arrows indicate the amino acid residues changed in mutants: L91F, D187N, and R269K. The tobacco Sulfur mutation is N269I.
