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

Functions as an aminopeptidase, with a clear preference for leucine as the N-terminal amino acid. However, can also cleave moderately long polypeptide substrates of various compositions in a fairly unspecific manner. Has neither carboxypeptidase nor endoproteolytic activities, and it is devoid of N-terminal deblocking activity. Is involved in protein degradation, performing degradation of oligopeptides produced by the proteasome into single amino acids.3 Publications

Miscellaneous

The hydrolytic mechanism is nonprocessive. Therefore, the enzyme does not process one substrate molecule completely before starting with another one. Instead, the reaction products are generated by multiple rounds of substrate digestion.

<p>This subsection of the 'Function' section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

Inhibited by EDTA and bestatin in vitro. Is insensitive to papain, antipain, chymostatin, leupeptin, pepstatin and aprotinin.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 7.5 with Leu-pNA as substrate. Strong activity is still detectable at pH 6 and 9.1 Publication

Temperature dependencei

Optimum temperature is 100 degrees Celsius over a broad pH array. At temperatures lower than 70 degrees Celsius, less than 10% of the maximum activity is detected. Highly thermostable. Shows half-lives of 24.8 minutes and 10.03 hours when incubated at 100 and 80 degrees Celsius, respectively.1 Publication

Homododecamer. The assembly of six dimers results in a tetrahedral-shaped structure; all 12 active sites are located on the inside of the tetrahedron. Substrate access is granted by four pores with a maximal diameter of 18 Angstroms, allowing only small peptides and unfolded proteins access to the active site. Beside the four entry ports, TET contains 12 small product release openings, which are large enough to allow passage of only single amino acid residues.

<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:iA6AE25809C8B2041
