Fig. 4From: In silico prospecting of the mtDNA of Macrobrachium amazonicum from transcriptome dataRepresentations of the three-dimensional structures of the mitochondrial-encoded proteins. A prominent characteristic of the α-helices (blue and orange) is the folding of the polypeptide skeleton around the main chain, while the β-sheets (red) are characterized by hydrogen bonds between the polypeptide chains, presenting a flat and rigid patternBack to article page
