The hydrolysis of glycylglycine (GylGly), glycyl-L-leucine (GlyLeu), L-leucylglycine (LeuGly)
and glycyl-DL-serine (GlySer) promoted by a copper (II)-cis, cis-1, 3, 5-triaminocyclohexane …

The copper (II), nickel (II) and zinc (II) binding ability of the multi-histidine peptide N-acetyl-
His-Pro-His-His-NH2 has been studied by combined pH-potentiometry and visible, CD and …

Complexing ability of tetrapeptides Phe–(R, S) HmR–Arg–Lys, Phe–(R) HmR–Arg–Lys and
Phe–(R, S) HmO–Arg–Lys containing potential multi-donor systems provided by the novel …

Potentiometry and UV–vis and circular dichroism spectroscopies were applied to
characterize Cu (II) coordination to the Ac-GASRHWKFL-NH2 peptide. Using HPLC and ESI …

Nickel (II), zinc (II) and cadmium (II) complexes of two N-terminally free hexapeptides
AAHAAC and AHAAAC containing separate histidyl and cysteinyl residues have been …

Introduction In 1951 Kroll discovered that Cu2+(and to a lesser extent Co2+ and Ni2+)
catalyzedthe hydrolysis of amino acid esters. 1 Li and co-workers2 and Bender and …

Artificial enzymes for site-specific hydrolyses of proteins or peptides are expected to be
novel tools for their structure analyses or functional regulations. Although a number of …

The protonation constants of the tripeptide glycylglycyl-L-histidine (L−) have been
determined at 25° C and I= 0.1 mol dm− 3 as log K 8.06, 6.82, and 2.80. Complexation with …

Previously we demonstrated that Ni (II) complexes of Ac-Thr-Glu-Ser-His-His-Lys-NH2
hexapeptide, representing residues 120-125 of human histone H2A, and some of its …

We report on the kinetics and mechanism of regioselective hydrolysis of amide bonds in
various dipeptides and tripeptides after these substrates react with [Pd (H 2 O) 3 (OH)]+ and …
