Primary sequence and post-transcriptional modification pattern of an unusual mitochondrial tRNA(Met) from Tetrahymena pyriformis.

abstract：:A large number of protein-protein interactions involved turn or loop regions. The excised linear peptides from these regions reveal complex conformational averaging. To circumvent this motional averaging and to stabilize the beta-turn conformation, extensive effort has been devoted to the design of constrained peptido...
