One residue of this amino acid in the eukaryotic elongation factor 2 is modified to formdipthamide, so named because diptheria attaches ADP-ribose to that special residue.
One residue of this amino acid in the eukaryotic elongation factor 2 is modified to formdipthamide, so named because diptheria attaches ADP-ribose to that special residue. Bacterialtwo component signal transduction systems primarily auto-phosphorylate this amino acid on thesensor-kinase protein. The catalytic triad of serine proteases consists of serine, aspartic acid, andthis amino acid. One of the most common type of (*) zinc finger motifs are defined by having twoconserved cysteines and two copies of this amino acid. The side chain of this amino acid has a pKaof about 6. For 10 points, name this amino acid with a imidazole side chain and whose single lettercode is H.
