Involved in an anaerobic respiration pathway that converts the sulfonate isethionate (2-hydroxyethanesulfonate) to ammonia, acetate and sulfide. Catalyzes the radical-mediated C-S bond cleavage of isethionate (2-hydroxyethanesulfonate) to form sulfite and acetaldehyde. Shows no activity with taurine or ethanolamine as substrates.1 Publication

    <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.
