ABSTRACT
|
|
|
| |
|
Papain (EC 3.4.22.2) is a proteolytic enzyme, the three-dimensional structure of
which has been determined by x-ray diffraction at 2.8 A resolution (Drenth, J.,
Jansonius, J.N., Koekoek, R., Swen, H. M., and Wothers, B.G. (1968), Nature
(London) 218, 929-932). The active site is a groove on the molecular surface in
which the essential sulfhydryl group of cysteine-25 is situated next to the
imidazole ring of histidine-159. The main object of this study was to determine
by the difference-Fourier technique the binding mode for the substrate in the
groove in order to explain the substrate specificity of the enzyme (P2 should
have a hydrophobic side chain (Berger and Schechter, 1970) and to contribute to
an elucidation of the catalytic mechanism. To this end, three chloromethyl
ketone substrate analogues were reacted with the enzyme by covalent attachment
to the sulfur atom of cysteine-25. The products crystallized isomorphously with
the parent structure that is not the native, active enzyme but a mixture of
oxidized papain (probably papain-SO2-) and papain with an extra cysteine
attached to cysteine-25. Although this made the interpretation of the difference
electron density maps less easy, it provided us with a clear picture of the way
in which the acyl part of the substrate binds in the active site groove. The
carbonyl oxygen of the P1 residue is near two potential hydrogen-bond donating
groups, the backbone NH of cysteine-25 and the NH2 of glutamine-19. Valine
residues 133 and 157 are responsible for the preference of papain in its
substrate splitting. By removing the methylene group that covalently attaches
the inhibitor molecules to the sulfur atom of cysteine-25 we obtained acceptable
models for the acyl-enzyme structure and for the tetrahedral intermediate. The
carbonyl oxygen of the P1 residue, carrying a formal negative charge in the
tetrahedral intermediate, is stabilized by formation of two hydrogen bonds with
the backbone NH of cysteine-25 and the NH2 group of glutamine-19. This situation
resembles that suggested for the proteolytic serine enzymes (Henderson, R.,
Wright, C. S., Hess, G. P., and Blow, D. M. (1971), Cold Spring Harbor Symp.
Quant. Biol. 36, 63-70; Robertus, J. D., Kraut, J., Alden, R. A., and Birktoft,
J. J. (1972b), Biochemistry 11, 4293-4303). The nitrogen atom of the scissile
peptide bond was found close to the imidazole ring of histidine-159, suggesting
a role for this ring in protonating the N atom of the leaving group (Lowe,
1970). This proton transfer would be facilitated by a 30 degrees rotation of the
ring around the C beta-Cgamma bond from an in-plane position with the sulfur
atom to an in-plane position with the N atom. The possibility of this rotation
is derived from a difference electron-density map for fully oxidizied papain vs.
the parent protein.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
Where a reference describes a PDB structure, the PDB
codes are
shown on the right.
