| tryptophan-trna ligase | <enzyme> An enzyme that activates tryptophan with its specific transfer RNA. Chemical name: L-Tryptophan:tRNA(Trp) ligase (AMP-forming) Registry number: EC 6.1.1.2 (12 Dec 1998) |
| tyrosine-trna ligase | <enzyme> An enzyme that activates tyrosine with its specific transfer RNA. Chemical name: L-Tyrosine:tRNA-(Tyr) ligase (AMP-forming) Registry number: EC 6.1.1.1 (12 Dec 1998) |
| expression site | The location in the genome of the gene for the variable surface glycoprotein that is currently being expressed (an expression-linked copy) by the trypanosome (a parasitic protozoan which causes the disease African sleeping sickness). most of these sites are near the ends, or telomeres, of a chromosome. (09 Oct 1997) |
| upstream activation site | A DNA sequence that regulates transcription like an enhancer but does notwork if its located downstream from a promoter. (09 Oct 1997) |
