Guanidination and amidination of bovine serum albumin, yeast enolase and yeast alcohol dehydrogenase were accompanied by increases in thermal stability at lower extents of modification. Decreases in thermal stability result from greater modification. These results support suggestions that surface guanidino groups arginyl groups are an important factor in thermal stability of proteins.

Amino acids that have secondary amino group attachments also react with ninhydrin. The essential groups of lysozyme, with particular reference to its reaction with iodine. The major modification from previous procedures is an extended TNBS reaction time to allow a stoichiometric reaction with amino groups. Tertiary structure of ribonuclease. Copyright and License information Disclaimer. They are soluble in water but not in nonpolar organic solvents such as cyclohexane. The amino acid phenylalanine also contains a benzene ring, but the ring is not activated and, therefore, does not readily undergo nitration. A procedure using 2,4,6-trinitrobenzenesulfonic acid TNBS for the determination of epsilon-amino groups in soluble and poorly soluble proteinaceous materials is presented. Oxygen toxicity, oxygen radicals, transition metals and disease. This nitration reaction, when used to identify the presence of an activated benzene ring, is commonly known as the xanthoproteic test, because the product is yellow.
