Descriptions Names[Advanced Search]

The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. Any macromolecular complex composed of two or more polypeptide subunits, which may or may not be identical. Protein complexes may have other associated non-protein prosthetic groups, such as nucleotides, metal ions or other small molecules. A DNA polymerase complex that contains two complexes of the catalytic alpha, beta, delta and epsilon polymerase/exonuclease subunits, plus the DnaX complex, a heptamer that includes the tau and gamma products of the dnaX gene and confers structural asymmetry that allows the polymerase to replicate both leading and lagging strands. A protein complex that possesses DNA polymerase activity and is involved in template directed synthesis of DNA. A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which the constituent parts function together. Any constituent part of a cell, the basic structural and functional unit of all organisms. Any constituent part of the living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. A heptamer that includes the tau and gamma products of the dnaX gene and the chi/psi subcomplex. Confers structural asymmetry that allows the polymerase to replicate both leading and lagging strands. A dimer composed of the chi and psi subunits which is a subassembly of the DNA polymerase III DnaX complex and serves as a bridge between the DnaX complex and the single-stranded DNA-binding protein (SSB).
