N-terminus - Wikipedia
The N-terminus (also known as the amino-terminus, NH 2-terminus, N-terminal end or amine-terminus) is the start of a protein or polypeptide, referring to the free amine group (-NH 2) located at the end of a polypeptide.
N-terminus and C-terminus in protein - ScienceQuery
2021年8月30日 · When a protein molecule is observed in a graphics program, the amino group that is visible with the lowest residue is the N-terminus. If a protein molecule is observed in a graphics program, the terminus that is visible with the highest residue is the C-terminus (1) & (5).
Introduction to N-terminus and C-terminus - Creative Proteomics
The N-terminus is the foremost segment of the protein to emerge from the ribosome during biosynthesis. It frequently harbors sequences serving as targeting signals, akin to intracellular postal codes, directing the protein to its designated cellular locale.

2017年7月26日 · Protein translocation to the endoplasmic reticulum starts with recognition of the signal peptide present at the N-terminus of the protein by a signal-recognition particle.
Analysis of N-terminus and C-terminus in Protein: A …
Proteins are composed of linear chains of amino acids, with each protein having two distinct ends: the N-terminus, featuring a free amine group, and the C-terminus, having a free carboxyl group. These termini are essential for the protein's function, stability, and interaction with other molecules. The analysis of these termini is crucial in ...
N-terminus - Vocab, Definition, and Must Know Facts - Fiveable
The n-terminus refers to the end of a protein or peptide chain that has a free amino group (-NH2). This is the starting point for protein synthesis, where amino acids are added during translation. The n-terminus is crucial for the proper functioning of proteins as it can affect the overall structure and interactions of the molecule.
N-Terminus - an overview | ScienceDirect Topics
The N-terminus is a specialized ‘landing pad’ for kinases transducing DNA damage signals. These kinases include the phosphatidyl-Inositol-3-Kinase family members ATM, ATR, DNA-PK, and the cell cycle regulatory kinases Chk1 and Chk2.
UNIT 11.10 N-Terminal Sequence Analysis of Proteins and Peptides
Automated N-terminal sequence analysis involves a series of chemical reactions that derivatize and remove one amino acid at a time from the N-terminal of purified peptides or intact proteins.
