“…ClustalW alignment [37] of rd proteins from G. theta (this work, CAB40406), Arabidopsis ([22], AAD25628), Synechocystis sp. strain PCC6803 ([7], BAA17090), Anabaena variabilis (unpublished, CAB45645), Azotobacter chroococcum ([38], P48343), Alcaligenes eutrophus ([39], P31912), Chlorobium limicola ([40], P09947), Butyribacterium methylotrophicum ([41], P14071), C. pasteurianum ([42], P00268), D. vulgaris ([43], P00269), Methylobacterium thermoautotrophicum ([44], AAB84661) and P. furiosus ([45], P24297) using the ‘blosum62’ weight matrix, a gap opening penalty of 20 and a gap extension penalty of 0.1. Conserved amino acids in all sequences are shaded black, conserved amino acids in at least 50% of the compared sequences are shaded gray.…”
