Organism
Photorhabdus laumondii subsp. laumondii (strain DSM 15139 / CIP 105565 / TT01)
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>
-Protein inferred from homologyi <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

Bifunctional enzyme that catalyzes the oxidative decarboxylation of UDP-glucuronic acid (UDP-GlcUA) to UDP-4-keto-arabinose (UDP-Ara4O) and the addition of a formyl group to UDP-4-amino-4-deoxy-L-arabinose (UDP-L-Ara4N) to form UDP-L-4-formamido-arabinose (UDP-L-Ara4FN). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides.UniRule annotation

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> section describes the catalytic activity of an enzyme, i.e. a chemical reaction that the enzyme catalyzes.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityi

This protein is involved in step 1 and 3 of the subpathway that synthesizes UDP-4-deoxy-4-formamido-beta-L-arabinose from UDP-alpha-D-glucuronate.UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Bifunctional polymyxin resistance protein ArnA (arnA)
  2. UDP-4-amino-4-deoxy-L-arabinose--oxoglutarate aminotransferase (arnB)
  3. Bifunctional polymyxin resistance protein ArnA (arnA)
This subpathway is part of the pathway UDP-4-deoxy-4-formamido-beta-L-arabinose biosynthesis, which is itself part of Nucleotide-sugar biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes UDP-4-deoxy-4-formamido-beta-L-arabinose from UDP-alpha-D-glucuronate, the pathway UDP-4-deoxy-4-formamido-beta-L-arabinose biosynthesis and in Nucleotide-sugar biosynthesis.

<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:i58D14182DBE14F65
