Enzyme class:
|
 |
E.C.4.2.99.18
- DNA-(apurinic or apyrimidinic site) lyase.
|
|
 |
 |
 |
 |
 |
Reaction:
|
 |
The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.

ABSTRACT
|
|
|
| |
|
Both 8oxo-guanine and formamidopyrimidines are major products of oxidative DNA
damage that can result in the fixation of transversion mutations following
replication if left unrepaired. These lesions are targeted by the N-DNA
glycosylase hOgg1, which catalyses excision of the aberrant base followed by
cleavage of the phosphate backbone directly 5' to the resultant abasic site in a
context, dependent manner. We present the crystal structure of native hOgg1
refined to 2.15 A resolution that reveals a number of highly significant
conformational changes on association with DNA that are clearly required for
substrate recognition and specificity. Changes of this magnitude appear to be
unique to hOgg1 and have not been observed in any of the DNA-glycosylase
structures analysed to date where both native and DNA-bound forms are available.
It has been possible to identify a mechanism whereby the catalytic residue Lys
249 is "primed" for nucleophilic attack of the N-glycosidic bond.

Figure 3. Conformational changes on DNA binding.
(a) The conformation of His270 in native and DNA-
bound structures together with interactions involving
Gln315, Phe319 and Asp322 which form a trigger mech-
anism that switches between closed and open states of
the 8oxoG binding pocket. (b) Changes occurring in
both the 8oxoG and cytosine recognition sites are
effected by residues in the interhelical segment along
with Arg204 and Asn149. The most significant of these
involves the side-chain amide oxygen atom of Asn149,
which, in the native structure, forms a direct hydrogen
bond to Lys249, but is flipped by
9
A
Ê
to interact with
the estranged cytosine base in the DNA-bound struc-
ture. The protein in the complex structure has a
Lys
!
Gln mutation at position 249. (c) Hydrogen
bonds from Asp268 and Asn149 to N
e
of Lys249 are
both broken by the conformational changes that occur
on DNA binding, leaving the catalytic lysine residue
with a neutral amino group, ready for nucleophilic
attack.

Figure 4.
Figure 4. Mutagenesis of Asp268. Mutation of Asp268
to either asparagine or alanine results in the almost
complete abolition of 8oxoG cleavage activity that is
consistent with Asp268 having a key catalytic role.

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.
