Protein

ESX-1 secretion system protein EccCb1

Gene

eccCb1

Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Reviewed-Annotation score:

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.

Part of the ESX-1 specialized secretion system, which delivers several virulence factors to host cells during infection, including the key virulence factors EsxA (ESAT-6) and EsxB (CFP-10) (PubMed:14557547, PubMed:14557536, PubMed:16368961, PubMed:16973880). EccCb1 may link the cytosolic components of the system with the membrane components (PubMed:16973880).1 Publication3 Publications

Miscellaneous

In ESX-1 cluster, the FtsK/SpoIIIE-like protein is split in two genes.Curated
Was identified as a high-confidence drug target.1 Publication

EsxB binding to the second FtsK domain of EccCb1 causes multimerization; a subsequent unknown step relieves the allosteric inhibition of linker 2 on FtsK domain 1 (in EccCa1 subunit), activating the ATPase activity (PubMed:25865481).1 Publication

<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.
