WebProteins have four levels of organization. Primary structure refers to the linear sequence of the amino acids connected by the peptide bonds. The secondary structure consists of local packing of polypeptide chain into α-helices and β-sheets due to hydrogen bonds between peptide bond – central carbon backbone. Tertiary (3D) structure is a ... WebThe μE motifs of the immunoglobulin μ heavy-chain gene enhancer bind ubiquitously expressed proteins of the basic helix-loop-helix (bHLH) family. These elements work together with other, more tissue-restricted elements to produce B-cell-specific enhancer activity by presently undefined combinatorial mechanisms.
