Annotation score:5 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. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Active toward triacylglycerides with a preference for esters with C8:0 acyl groups; barely active on C18:1 or C18:4 substrates. Active against p-nitrophenylesters with fatty acid chain lengths from C6 to C18.

<p>This subsection of the <a href="http://www.uniprot.org/help/function%5Fsection">Function</a> section describes regulatory mechanisms for enzymes, transporters or microbial transcription factors, and reports the components which regulate (by activation or inhibition) the reaction.<p><a href='/help/activity_regulation' target='_top'>More...</a></p>Activity regulationi

Strongly inhibited when incubated with the serine reagent phenylmethylsulfonyl fluoride. Activated by the addition of calcium to the reaction mixture. When calcium was incubated with the lipase but not added to the reaction mixture, its effect is lower but still observable. Magnesium, manganese and strontium are not able to replace calcium with full retention of activity.1 Publication

<p>This subsection of the 'Function' section describes biophysical and chemical properties, such as maximal absorption, kinetic parameters, pH dependence, redox potentials and temperature dependence.<p><a href='/help/biophysicochemical_properties' target='_top'>More...</a></p>pH dependencei

Optimum pH is 10 (PubMed:11029590). The activity decreases strongly above pH 10.5 or below pH 6.5. The enzyme is remarkably stable at alkaline pH, showing maximum stability at pH 12 and retaining more than 65% of its activity after 24 hours at pH 13 (PubMed:8396026).2 Publications

Temperature dependencei

Optimum temperature is 35 degrees Celsius. Stable for at least 30 minutes at 40 degrees Celsius. Virtually no activity remains after 30 minutes at 55 degrees Celsius.2 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. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iB8A70E027461188F
