Polypeptides

Some articles on polypeptides, polypeptide:

Antiparallel (biochemistry) - Polypeptides - Beta Sheet
... In beta sheets, sections of a single polypeptide may run side-by-side and antiparallel to each other, to allow for hydrogen bonding between their carbon backbone ...
Translocon
... is the complex of proteins associated with the translocation of nascent polypeptides across membranes ... In eukaryotes the polypeptides are transported into the interior (cisternal or luminal) space of the endoplasmic reticulum (ER) from the cytosol ... In prokaryotes, a similar protein complex transports polypeptides across the plasma membrane ...
NACA (gene) - Function
... nascent) ribosome-associated polypeptides from inappropriate interactions with cytosolic proteins ... NACA binds nascent-polypeptide domains emerging from ribosomes unless it contains a signal peptide which is fully exposed ... of NACA from ribosomes carrying nascent polypeptides allows the signal recognition particle (SRP) to crosslink to polypeptides regardless of whether or not they contain ...
Gel Electrophoresis Of Proteins - Denaturing Gel Methods - SDS-PAGE
... according to their electrophoretic mobility (a function of the length of a polypeptide chain and its charge) while in the denatured (unfolded) state ... In most proteins, the binding of SDS to the polypeptide chain imparts an even distribution of charge per unit mass, thereby resulting in a ... strong detergent agent used to denature native proteins to unfolded, individual polypeptides ...
