Molecular biology
antioxidant
Biology; Biochemistry
A scavenger of reactive oxygen free radical species (OH · , O 2 -· , etc.) and other oxidizing compounds; of particular importance are those that act as antioxidants in vivo, e.g. ascorbate, ...
lipid peroxidation
Biology; Biochemistry
The oxidation of polyunsaturated fatty acid side chains, initiated by a free radical such as the hydroxyl radical (OH ), to form a relatively stable carbon free radical, which reacts further with ...
epitope
Biology; Biochemistry
The antigenic determinant; i.e. that part of an antigen to which an antibody is directed; it defines the specificity of the antigen and consequently binds to the receptor on a T-cell or to the ...
Velcro mechanism
Biology; Biochemistry
An activation mechanism for matrix metalloproteinase family zymogens (named in reference to the zipper-type mechanism), in which the thiol group of a cysteine residue in the N-terminal propart binds ...
cysteine switch
Biology; Biochemistry
An activation mechanism for matrix metalloproteinase family zymogens (named in reference to the zipper-type mechanism), in which the thiol group of a cysteine residue in the N-terminal propart binds ...
informational RNA (iRNA)
Biology; Biochemistry
Essentially, intronic sequences of hnRNA, for which an evolutionary function has been proposed: by a mechanism analogous to the SELEX procedure, and in the absence of any conservative selective ...
nuclear receptor
Biology; Biochemistry
A nuclear protein that allows regulation of gene expression by a lipophilic effector molecule, such as a steroid or thyroid hormone, eicosanoid, retinoid or ecdysone. When the effector molecule is ...
