IPR013097 is a Stress responsive alpha-beta barrel.
<p>The stress-response A/B barrel domain is found in a class of stress-response proteins in plants. It is also found in some bacterial fructose-bisphosphate aldolase such as at the C terminus of a fructose 1,6-bisphosphate aldolase from Hydrogenophilus thermoluteolus ([swissprot:Q9ZA13]) [[cite:PUB00016501]]. [swissprot:Q93NG5] is found in the pA01 plasmid, which encodes genes for molybdopterin uptake and degradation of plant alkaloid nicotine.</p> <p>The stress-response A/B barrel domain forms a very stable dimer. This dimer belongs to the superfamily of dimeric α+β barrels in which the two β-sheets form a β-barrel. The two molecules in the dimer are related by a 2-fold axis parallel to helix H1 and β-strands B3 and B4. C-terminal residues extending from the beta4 strand of each monomer wrap around and connect with the beta2 strand and alpha1 helix of the opposing monomer to form the dimer interface [[cite:PUB00031274], [cite:PUB00022615], [cite:PUB00031070]].The outer surface of the β-sheets of the two molecules forms a β-barrel-like structure defining a central pore.</p> <p>The function of the stress-response A/B barrel domain is unknown [[cite:PUB00031274], [cite:PUB00022615], [cite:PUB00031070]], but it is upregulated in response to salt stress in Populus balsamifera (balsam poplar) [[cite:PUB00016419]].</p> <p>Some proteins known to contain a stress response A/B barrel domain are listed below:</p> <ul> <li>Arabidopsis thaliana At3g17210</li> <li>Arabidopsis thaliana At5g22580</li> <li>Populus tremula stable protein 1 (SP-1)(Populus species), a thermostable stress-responsive protein.</li> <li>Pseudomonas hydrogenothermophila fructose 1,6-bisphosphate aldolase (cbbA).</li> </ul> <p>The structure of one of these proteins has been solved ([swissprot:Q9LUV2]) and the domain forms an α-β barrel dimer [[cite:PUB00016433]].</p>
