Screening was carried out for microorganisms able to produce N-(l-alpha-l-aspartyl)-l-phenylalanine methyl ester [APM] from l-isoasparagine and l-phenylalanine methyl ester hydrochloride. Of the 422 strains examined, 44 strains belonging to the family Enterobacteriaceae were found to produce APM. The enzyme catalyzing
The PST-01 protease is a metalloprotease that has zinc ion at the active center and is very stable in the presence of water-soluble organic solvents. The reaction rates and the equilibrium yields of the aspartame precursor N-carbobenzoxy-L-aspartyl-L-phenylalanine methyl ester (Cbz-Asp-Phe-OMe)

1. Programmed cell death proceeds by an unknown mechanism which results in characteristic morphological changes known as apoptosis. 2. We have proposed that, in hormone-induced apoptosis, cell death may be the result of an attack of cells destined to die

Molecularly imprinted polymers are highly stable and can be sterilised, making them ideal for use in biotransformation process. In this communication, we describe a novel application of molecularly imprinted polymers in an enzymatic reaction. The enzymatic condensation of Z-L-aspartic acid
Monocytes macrophages have negative regulatory effects on many immunologic responses. Depletion of monocytes from peripheral blood using the lysosomotropic agent, L-phenylalanine methyl ester (PME), has been shown to improve lymphokine activated killer (LAK) cell expansion in vitro. A pilot study
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
