Peptide Bond Formation between Aminoacyl-Minihelices by a Scaffold Derived from the Peptidyl Transferase Center

Life, 2022
The peptidyl transferase center (PTC) in the ribosome is composed of two symmetrically arranged tRNA-like units that contribute to peptide bond formation.

Efficient processing of an antigenic sequence for presentation by MHC class I molecules depends on its neighboring residues in the protein [PDF]

, 1991
Processing of endogenously synthesized proteins generates short peptides that are presented by MHC class I molecules to CD8 T lymphocytes. Here it is documented that not only the sequence of the presented peptide but also the residues by which it is ...

Exploiting Peptide Self-Assembly for the Development of Minimalistic Viral Mimetics

Frontiers in Chemistry, 2021
Viruses are natural supramolecular nanostructures that form spontaneously by molecular self-assembly of complex biomolecules. Peptide self-assembly is a versatile tool that allows mimicking viruses by creating their simplified versions through the design

Aminopeptidase C of Aspergillus niger is a Novel Phenylalanine Aminopeptidase [PDF]

, 2003
A novel enzyme with a specific phenylalanine aminopeptidase activity (ApsC) from Aspergillus niger (CBS 120.49) has been characterized. The derived amino acid sequence is not similar to any previously characterized aminopeptidase sequence but does share ...

Solution to peptide sequencing challenge [PDF]

Analytical and Bioanalytical Chemistry, 2013
The cyclic peptide described is kalata B1 [1, 2] and its structure is shown in Fig. 1. The partial reduction of the cyclic peptide [2, 3] allows one to establish the disulfide connectivity. The first peptide is amino-ethylated at only {2}Cys and {5}Cys, whereas the second peptide is amino-ethylated at only {1}Cys and {4}Cys.
