The structural accessibility of tryptophan residues in leucyl-tRNA synthetase from cow mammary gland has been studied using chemical modifications by N-bromosuccinimide and 2-hydroxy-5-nitrobenzyl bromide. The modifications were monitored by UV absorbance and intrinsic fluorescence of the enzyme's tryptophan residues. Under
