Protein

Mono(2-hydroxyethyl) terephthalate hydrolase

Gene

ISF6_0224

Organism
Ideonella sakaiensis (strain 201-F6)
Status
Reviewed-Annotation score:

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>

Involved in the degradation and assimilation of the plastic poly(ethylene terephthalate) (PET), which allows I.sakaiensis to use PET as its major energy and carbon source for growth. Likely acts synergistically with PETase to depolymerize PET. Catalyzes the hydrolysis of mono(2-hydroxyethyl) terephthalate into its two environmentally benign monomers, terephthalate and ethylene glycol. Does not show activity against PET, bis(hydroxyethyl) terephthalate (BHET), pNP-aliphatic esters or typical aromatic ester compounds catalyzed by the tannase family enzymes, such as ethyl gallate and ethyl ferulate.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.
