Annotation score:4 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Putative thioesterase. Does not bind pectin, and has no pectinesterase activity.2 Publications

Caution

Lacks the conserved Asp residue in position 252 essential for pectinase activity. Likewise, most of the residues involved in substrate binding are not conserved. Was originally (PubMed:15808744) thought to have palmitoyl-CoA thioesterase activity, but PubMed:19452549 were unable to detect any pectinase or palmitoyl-CoA thioesterase activity. Its enzyme activity is therefore unsure.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.
