Degrades abnormal exported proteins and responsible for the propeptide processing of a natural pro-protein and for the maturation of a native protein. It also plays a prominent role in stress (heat shock, ethanol, puromycin and NaCl) resistance during active exponential growth (Probable).1 Publication

Miscellaneous

Inactivation results in compensating overexpression of YtvA, especially during stress conditions.

<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.
