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.

<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

Along with the bacABCDEF operon, BacG is involved in the biosynthesis of the nonribosomally synthesized dipeptide antibiotic bacilysin, composed of L-alanine and L-anticapsin. Bacilysin is an irreversible inactivator of the glutaminase domain of glucosamine synthetase (PubMed:20052993).

BacG catalyzes the stereoselective reduction of exocyclic-delta3,delta5-dihydro-hydroxyphenylpyruvate (ex-H2HPP), adding a pro-S hydride equivalent to C4 position to yield tetrahydro-hydroxyphenylpyruvate (H4HPP) (PubMed:22765234, PubMed:23519407).

Although the 3Z,7R-ex-H2HPP isomer is kinetically disfavored by BacB and produced in a smaller quantity than 3E,7R-ex-H2HPP, it is the preferred substrate for the conjugate reduction reaction of BacG (PubMed:22765234, PubMed:23519407).

<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.
