Description

IPR033130 is a Ribonuclease T2, His active site 2.

<p>The fungal ribonucleases T2 from Aspergillus oryzae, M from Aspergillus saitoi and Rh from Rhizopeus niveus are structurally and functionally related 30 Kd glycoproteins [[cite:PUB00002342]] that cleave the 3'-5' internucleotide linkage of RNA via a nucleotide 2',3'-cyclic phosphate intermediates ([ec:3.1.27.1]).</p> <p>A number of other RNAses have been found to be evolutionary related to these fungal enzymes:</p> <ul> <li>Self-incompatibility [[cite:PUB00005134]] in flowering plants is often controlled by a single gene (S-gene) that has several alleles. This gene prevents fertilization by self-pollen or by pollen bearing either of the two S- alleles expressed in the style. The self-incompatibility glycoprotein from several higher plants of the solanaceae family has been shown [[cite:PUB00005134], [cite:PUB00004051]] to be a ribonuclease.</li> <li>Phosphate-starvation induced RNAses LE and LX from tomato [[cite:PUB00001441]]. These two enzymes are probably involved in a phosphate-starvation rescue system.</li> <li>Escherichia coli periplasmic RNAse I (EC 3.1.27.6) (gene rna) [[cite:PUB00001796]].</li> <li>Aeromonas hydrophila periplasmic RNAse.</li> <li>Haemophilus influenzae hypothetical protein HI0526.</li> </ul> <p>Two histidines residues have been shown [[cite:PUB00001381], [cite:PUB00001640]] to be involved in the catalytic mechanism of RNase T2 and Rh. These residues and the region around them are highly conserved.</p>
