Structural features of dna binding proteins
WebApr 4, 2009 · DNA binding proteins (DBPs) often take part in various crucial processes of the cell's life cycle. Therefore, the identification and characterization of these proteins are of great importance. We present here a random forests classifier for identifying DBPs among proteins with known three-dimensional structures. WebNow let’s consider the structure of the two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base ( Figure 9.3 ). There are four types of nitrogenous bases in DNA.

WebJan 15, 2003 · The structures of very small protein domains are generally stabilized by the formation of disulfide bonds, or by binding to metal ions (most frequently, zinc). Metal binding increases the thermal and conformational stability of small domains but typically is not directly involved in their function.
WebProteins that bind both DNA and RNA typify the ability of a single gene product to perform multiple functions. Such DNA- and RNA-binding proteins (DRBPs) have unique functional characteristics that stem from their specific structural features; these developed early in evolution and are widely conserved.
