Abstract:Tricopeptide repeats are common in natural proteins, and are exemplified by 34- and 35-residue repeats, known respectively as tetratricopeptide repeats (TPRs) and pentatricopeptide repeats (PPRs). In both classes, each repeat unit forms an antiparallel bihelical structure, so that multiple such units in a polypeptide are arranged in a parallel fashion. The primary structures of the motifs are nonidentical, but amino acids of similar properties occur in strategic positions. The focus of the present work was on … Show more
“…Barik [ 2 ] offered a detailed analytical and comparative review of a special kind of protein motif, found as repeats that are commonly 34- and 35-amino acid residues long, and are known, respectively, as tetratricopeptide (TPRs) and pentatricopeptide repeats (PPRs). Both repeats are common in natural proteins, PPRs being particularly abundant in plants.…”
