THE PROTEIN DOMAIN IS A FUNDAMENTAL UNIT OF ORGANIZATION
by Abbi Pineda
1. The protein domains are structural repetitions within a protein that can fold independently it is a stable structure.
2. Stretches of polypeptide chain that from a: Alphahelices and Beta sheets constitute the protein’s secondary structure.
3. The differents domains of a protein are often associated with different functions. A protein formed from four domains.
4. A small protein molecule is built from thousands of atoms linked together by precisely oriented covalent and noncovalent bonds
5. The amino acid sequence is known as the primary structure of the protein
6. A domain usually contains between 40 and 350 aminoacids, and it’s the modular unit from which many larger proteins are constructed.
