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>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Involved in both the tricarboxylic acid (TCA) and methylcitric acid cycles (PubMed:28956599). Has both 2-methylcitrate synthase and citrate synthase activities. Catalyzes the condensation of propionyl-CoA and oxaloacetate to yield 2-methylcitrate (2-MC) and CoA, and the condensation of acetyl-CoA and oxaloacetate to yield citrate and CoA (PubMed:8759838, PubMed:28956599). Has 2.3-fold higher activity as a 2-methylcitrate synthase (PubMed:28956599). Catalyzes the formation of either (2S,3R)- or (2R,3S)-2-methylcitrate (PubMed:28956599).2 Publications

Miscellaneous

Bifunctionality as a citrate and 2-methylcitrate synthase is likely important in the mother cell's physiological milieu.1 Publication

This protein is involved in step 1 of the subpathway that synthesizes isocitrate from oxaloacetate.1 Publication
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Citrate synthase 2 (citZ), Citrate synthase 1 (citA), Citrate/2-methylcitrate synthase (mmgD)
  2. Aconitate hydratase (acnA), Aconitate/2-methylaconitate hydratase (citB)
This subpathway is part of the pathway tricarboxylic acid cycle, which is itself part of Carbohydrate metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes isocitrate from oxaloacetate, the pathway tricarboxylic acid cycle and in Carbohydrate metabolism.

<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:i29FD292E27B5F9F7
