Protein Structure

Overview Proteins are chains of amino acids that are connected by peptide bonds and folded into a 3-dimensional structure. The side chains of individual …

Overview Proteins are one of the fundamental building blocks of life that carry out many diverse functions in the cell. Proteins are assembled from amino …

Overview Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation which …

Protein families are groups of homologous proteins; that is, they have similarities in amino acid sequences and three-dimensional structures. Protein …

Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally …

Many proteins can be classified into two distinct subtypes – globular or fibrous. These two types differ in their shapes and solubilities. Globular …

Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows …

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes …

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with …

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or …

Overview Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced …
