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.

Involved in the breakdown of putrescine via the biosynthesis of gamma-L-glutamylputrescine. It is able to use several diamines, spermidine and spermine. Absolutely essential to utilize putrescine as both nitrogen and carbon sources and to decrease the toxicity of putrescine, which can lead to inhibition of cell growth and protein synthesis.2 Publications

This protein is involved in step 1 of the subpathway that synthesizes 4-aminobutanoate from putrescine.
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Gamma-glutamylputrescine synthetase PuuA (puuA)
  2. Gamma-glutamylputrescine oxidoreductase (puuB)
  3. NADP/NAD-dependent aldehyde dehydrogenase PuuC (puuC)
  4. Gamma-glutamyl-gamma-aminobutyrate hydrolase PuuD (puuD)
This subpathway is part of the pathway putrescine degradation, which is itself part of Amine and polyamine degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 4-aminobutanoate from putrescine, the pathway putrescine degradation and in Amine and polyamine degradation.

<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.
