Non-protein amino acids in peptide design (2003)

Aravinda, S, Shamala, N, Roy, Rituparna S, Balaram, P

An overview of the use of non-protein amino acids in the design of conformationally well-defined peptides, based on work from the author’s laboratory, is discussed. The crystal structures of...

Beta-Hairpins Generated from Hybrid Peptide Sequences Containing both Alpha- and Beta-Amino Acids (2002)

Hosahudya, Gopi N, Roy, Rituparna S, Raghothama, Srinivasa R, Karle, Isabella L

The incorporation of the -amino acid residues into specific positions in the strands and -turn segments of peptide hairpins is being systematically explored. The presence of an additional torsion...
