Molecular biology
electron nuclear double resonance (ENDOR)
Biology; Biochemistry
A technique for detection of coupling between electrons and nuclei in order to gain information about the valance electron distribution around a paramagnetic nucleus; observation of an electron spin ...
Yin-Yang hypothesis
Biology; Biochemistry
The now-abandoned theory that bidirectional cellular processes, i.e. those that involve two individual pathways (rather than one that may be 'on' or 'off'), e.g. proliferation/ contact inhibition, ...
non-collagen collagen
Biology; Biochemistry
A protein complex that, like collagen, has (Xaa-Yaa-Gly) n amino acid sequences and non-helical globular regions. The collagen-like sequences assemble together into a triple helix and the globular ...
specificity constant (kcat/Km)
Biology; Biochemistry
The apparent second-order rate constant for enzyme action under conditions where an enzyme's binding site is largely unoccupied by substrate ((S)≪K m ); equivalent to the slope of the (pseudo) ...
protein ruler
Biology; Biochemistry
A high-molecular-mass protein that functions in organization of cytoskeletal structures of uniform length by serving as a template for aggregation of exact numbers of other components of the ...
complementarity-determining region (CDR)
Biology; Biochemistry
A polypeptide sequence of a variable domain of an immunoglobulin that is particularly responsible for its recognition by lymphocytes. These short sequences interrupt and loop out from the framework ...
Y-joint
Biology; Biochemistry
A DNA heteroduplex structure in which one strand is extended by a non-homologous internal sequence. The loop of the longer strand is base-paired with itself in a hairpin structure. In an open Y-joint ...
