Allosteric Site definition: A site on an enzyme which upon binding of a modulator, causes the enzyme to undergo a conformational change that may alter its catalytic or binding properties.
allosteric site definition: enzyme site which binds molecule other than substrate, thereby regulating enzyme activity.
Attachment Sites, Microbiological definition: Specific loci on both the bacterial DNA (attB) and the phage DNA (attP) which delineate the sites where recombination takes place between them, as the phage DNA becomes integrated (inserted) into the BACTERIAL DNA during LYSOGENY.
Binding Sites definition: The parts of a macromolecule that directly participate in its specific combination with another molecule.
binding site definition: reactive portion of a macromolecule that directly participates in its specific combination with another molecule.
Binding Sites, Antibody definition: Local surface sites on antibodies which react with antigen determinant sites on antigens. They are formed from parts of the variable regions of FAB FRAGMENTS.
Antibody Binding Site definition: The site at which an antibody makes direct physical contact with a corresponding epitope on an antigen.
Neoplasms by Site definition: A collective term for precoordinated organ/neoplasm headings locating neoplasms by organ, as BRAIN NEOPLASMS; DUODENAL NEOPLASMS; LIVER NEOPLASMS; etc.
cholinergic receptor definition: since the 2 subtypes are distinctly different receptors, use MUSCARINIC or NICOTINIC whenever possible; use this general term only for unspecified binding of acetylcholine and related ligands.
Receptors, Cholinergic definition: Cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. Cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. Each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.
