| charge transfer system | A complex between two organic molecules in which an electron from one (the donor) is transferred to the other (the acceptor), becoming generally distributed throughout the latter; subsequent transfer of a hydrogen atom completes the reduction of the acceptor; such complex's are generally highly coloured and may be so observed, a network of hydrogen bridges at the catalytic centre of certain proteases. Synonym: charge transfer system. (05 Mar 2000) |

| group transfer | The transfer of a functional moiety from one molecule to another. (05 Mar 2000) |
| RNA, transfer | In cooperation with the ribosomes, transfer RNA brings (transfers) activated amino acids into position along the messenger RNA template. The abbreviation for transfer RNA is trna. (12 Dec 1998) |
| RNA, transfer, ala | A transfer RNA which is specific for carrying alanine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, amino acid-specific | A group of transfer rnas which are specific for carrying each one of the 20 amino acids to the ribosome in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, amino acyl | Intermediates in protein biosynthesis. The compounds are formed from amino acids, ATP and transfer RNA, a reaction catalyzed by aminoacyl trna synthetase. They are key compounds in the genetic translation process. (12 Dec 1998) |
