Snake venom phospholipase A2 (PLA2) that displays edema-inducing activities (activity that is inhibited by EDTA and dexamethasone), inhibits phospholipid-dependent collagen/ADP-induced platelet aggregation, possess hypotensive as well as anticoagulant activities. In addition, this enzyme shows bactericidal activity against E.coli and S.aureus. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.3 Publications

<p>The checksum is a form of redundancy check that is calculated
from the sequence. It is useful for tracking sequence updates.</p>
<p>It should be noted that while, in theory, two different sequences could
have the same checksum value, the likelihood that this would happen
is extremely low.</p>
<p>However UniProtKB may contain entries with identical sequences in case
of multiple genes (paralogs).</p>
<p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64)
using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
The algorithm is described in the ISO 3309 standard.
