Liberation of lysine by acid and enzymes from heated lysine-glucose mixture.
Studies on the formation of humin in protein hydrolysates have demonstrated that heating causes a reaction between carbohydrates and certain amino acids (l-3). This reaction, often referred to as the Maillard reaction, has significance in connection with the development of brown color during the processing of foods. Further, this reaction appears to have nutritional importance, since recently i...
متن کاملLantibiotic structures as guidelines for the design of peptides that can be modified by lantibiotic enzymes.
Lantibiotics are (methyl)lanthionine-containing bacterial peptides. (Methyl)lanthionines are posttranslationally introduced into the prepropeptides by biosynthetic enzymes that dehydrate serines and threonines and couple these dehydrated residues to cysteine residues. Thirty seven lantibiotic primary structures have been proposed to date, but little is known about the substrate specificity of t...
متن کاملEngineering nicking enzymes that preferentially nick 5-methylcytosine-modified DNA
N.ϕGamma is a strand-specific and site-specific DNA nicking enzyme (YCG↓GT or AC↑CGR). Here we describe the isolation of single and double mutants of N.ϕGamma with attenuated activity. The nicking domains (NDs) of E59A and 11 double mutants were fused to the 5mCG-binding domain of MBD2 and generated fusion enzymes that preferentially nick 5mCG-modified DNA. The CG dinucleotide can be modified b...

متن کاملIsomerization of Glucose to Fructose
In the previous paper, one of the authors described "A Survey on the Dextrose Industry in Japan and its Future" in the 1967 issue. As shown in the earlier paper, the supply and demand situation of starch in this country was drastically changed since 1963-64. In the later 1950's, the Japanese Government had a big problem to eliminate the big stock of the over-produced sweet potato starch. Theref...
