Molecular biology

Descriptive of the orientation of a substituent on a six-membered ring that is perpendicular to the plane of the ring; the opposite of equatorial, which is the orientation substantially within the ...

molecular matchmaker

Biology; Biochemistry

A protein that effects complex-formation between another protein and DNA by catalysis of an energy-dependent conformational change in at least one of the pair; it thereby increases affinity and ...

RNA chaperone

Biology; Biochemistry

A putative RNA-binding protein that assists RNA in attainment of its biologically active conformation. Non-specific RNA-binding proteins are proposed to prevent RNA becoming temporarily trapped in ...

(A+T)/(G+C) ratio

Biology; Biochemistry

A reference to the base composition of double-stranded DNA. DNA from different sources has different ratios of the A-to-T and G-to-C base pairs, e.g. DNAs isolated from organisms that live in hot ...

proton motive force

Biology; Biochemistry

The free energy, expressed in volts, represented by a pH gradient across the membrane of a vesicle due to the concentration gradient plus the membrane potential. This energy is used by coupling the ...

trans-acting

Biology; Biochemistry

Descriptive of a controlling effect of a regulatory gene on a structural gene at some distance from it on the same chromosome or on a different chromosome. The terminology was later broadened to ...

acceptor

Biology; Biochemistry

In enzyme mechanisms, a functional group of an enzyme that transiently receives a moiety of a substrate, the donor, before itself becoming a donor in transferring it to a second substrate, which is ...
