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>

Chemotactic-signal transducers respond to changes in the concentration of attractants and repellents in the environment, transduce a signal from the outside to the inside of the cell, and facilitate sensory adaptation through the variation of the level of methylation. All amino acids serve as attractants in B.subtilis, they appear to cause an increase in the turnover methyl groups, leading to methylation of an unidentified acceptor, while repellents have been shown to cause a decrease in methyl group turnover. The methyl groups are added by a methyltransferase and removed by a methylesterase. McpB is required for taxis towards asparagine, aspartate, glutamine, and histidine.1 Publication

Miscellaneous

Only chemotaxis towards asparagine is completely deficient in the absence of McpB.

Some glutamine residues are deamidated to glutamate by CheD and subsequently methylated.3 Publications
The demethylation is selective. Gln-371 is demethylated only upon asparagine addition whereas Glu-637 is demethylated only upon asparagine removal. Glu-630 appears indiscriminate and is demethylated upon both addition and removal of asparagine.

<p>The checksum is a form of redundancy check that is calculated from the sequence.
