Tryptophan residues
WebThe modification of tryptophan residues in proteins may occur at a more limited number of sites in vivo than that of tyrosine residues, since tryptophan residues are more buried … WebSep 15, 2008 · Hydrolysis of Mb ox followed by amino acid analysis indicated that methionine (Met) and tryptophan (Trp) residues were modified by HOCl. Peptide mass mapping revealed that Met55 was oxidized at a lower HOCl/Mb ratio than Met131 and this preceded Trp7/14 modification (susceptibility Met55 > Met131 > Trp7 > Trp14).

WebJan 25, 2010 · It was demonstrated by NMR that the ethynylation occurred selectively at the C2-position of the indole ring of tryptophan, and MS/MS showed that the tryPTophan residues could be modified selectively with Ethynyl functionalities even when the tryptophile was present as a part of the protein. Expand WebSeveral tryptophan residues interact via cation–π interactions with arginine residues which in turn form salt bridges with acidic residues on a second copy of the protein. It has been proposed that absorption of a photon by the tryptophan residues disrupts this interaction and leads to dissociation of the protein dimer.
