Low barrier hydrogen bond is absent in the catalytic triads in the ground state but Is present in a transition-state complex in the prolyl oligopeptidase family of serine proteases
Kahyaoglu A, Haghjoo K, Guo F, Jordan F, Kettner C, Felfoldi F, et al.
J Biol Chem . 1997 Nov; 272(41):25547-54. PMID: 9325271
High frequency proton NMR spectra for two members of the prolyl oligopeptidase class of serine proteases, prolyl oligopeptidase and oligopeptidase B, showed that resonances corresponding to the active center histidine...

Benzyloxycarbonylprolylprolinal, a transition-state analogue for prolyl oligopeptidase, forms a tetrahedral adduct with catalytic serine, not a reactive cysteine
Kahyaoglu A, Haghjoo K, Kraicsovits F, Jordan F, Polgar L
Biochem J . 1997 Mar; 322 ( Pt 3):839-43. PMID: 9148758
N-Benzyloxycarbonyl-l-prolyl-l-[1-13C]prolinal was synthesized starting with reduction of l-[1-13C]Pro to l-[1-13C]prolinol, followed by coupling with N-benzyloxycarbonyl-l-Pro to N-benzyloxycarbonyl-l-Pro-l-[1-13C]prolinol (Z-Pro-[1-13C]prolinol), and finally oxidation of the alcohol to the aldehyde with dimethyl sulphoxide....

Solution structure of vasoactive intestinal polypeptide (11-28)-NH2, a fragment with analgesic properties
Haghjoo K, Cash P, Farid R, Komisaruk B, Jordan F, Pochapsky S
Pept Res . 1996 Nov; 9(6):327-31. PMID: 9048428
An 18-residue-long fragment of vasoactive intestinal polypeptide [VIP(11-28)-NH2] that is known to be analgesic was synthesized by solid-phase t-Boc methodology on a 4-methylbenzhydrylamine resin. Circular dichroism spectroscopy gave evidence that...

Further evidence for the structure of the subtilisin propeptide and for its interactions with mature subtilisin
Hu Z, Haghjoo K, Jordan F
J Biol Chem . 1996 Feb; 271(7):3375-84. PMID: 8631936
Evidence is presented for some secondary structure, very likely alpha-helical, of the propeptide of subtilisin E in aqueous salt solution, as well as for strong intermolecular interactions between the propeptide...
