The dipeptide sequence at the carboxy-terminal of a heavy (μ) chain from a human macroglobulin (IgM) is tyrosylcysteine, although the reverse sequence, cysteinyltyrosine, has not been rigorously ...

This is a preview. Log in through your library . Abstract Characterization of the unfolded state is essential for the understanding of the protein folding reaction. We performed time resolved FRET ...

Proteins are the key players that regulate cellular structure and function. DNA, which functions as the blueprint for protein synthesis, is first transcribed into a messenger RNA (mRNA), which is ...

For almost 40 years, researchers have been fascinated by the question of how proteins are transported across or are integrated into membranes. Pioneering work by G. Palade 1 demonstrated that in ...

An interdisciplinary team of scientists from Cologne, Heidelberg and Munich have discovered a new function of a well-known enzyme. The signal peptidase complex in the endoplasmic reticulum cleaves ...

Water-soluble peptides that adopt stable helical conformations are attractive motifs because of their importance in basic science and their broad utility in medicine and biotechnology. Incorporating ...

Just as children can strengthen ties between parents, ensuring the family stays together at least until they’re grown, a new study shows nascent polypeptide chains have the inherent ability to ensure ...

The human leukocyte antigens (HLA-I) are multi-subunit complexes that localize to the cell surface and present bound peptides to nearby immune cells. The study of these HLA peptide-presenting ...

An interdisciplinary team of scientists from Cologne, Heidelberg and Munich have discovered a new function of a well-known enzyme. The signal peptidase complex in the endoplasmic reticulum cleaves ...

Antibodies are proteins with around 150 kDa molecular weight. They have a similar basic structure comprising of four polypeptide chains held together by disulfide bonds. These four polypeptide chains ...
