Enantiomeric resolution and modeling of DL-alanine-DL-tryptophan dipeptide on amylose stationary phase
The enantiomeric resolution of DL-alanine-DL-tryptophan dipeptide is described on amylose stationary phase. The eluent used was CH3OH─CH3COONH4 (10mM)─CH3CN (50: 40, 10) at 0.8-mL/min flow, 230-nm detection, 25-

Methods of treatment using water-soluble tryptophan-containing peptides obtained by the hydrolysis of hens eggs lysozyme
The present invention relates to a process to produce a composition comprising water-soluble peptides and having a Trp/LNAA ratio of more than 0.15, which comprises hydrolyzing lysozyme, preferably hen eggs lysozyme, to prepare a hydrolysate having a DH of between 5 and 45.

Identification of novel L-amino acid α-ligases through hidden markov model-based profile analysis
L-Amino acid α-ligase (Lal), catalyzing the formation of α-dipeptides from unprotected l-amino acids in an ATP-dependent manner, is used in cost-effective fermentative production of dipeptides. We searched for novel Lals by in silico screening using Hidden Markov Model-based profile analysis, and identified five novel Lals that showed low similarity and different substrate specificity from known Lals.
