Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Essential cell division protein. May link together the upstream cell division proteins, which are predominantly cytoplasmic, with the downstream cell division proteins, which are predominantly periplasmic. Can also mediate Zn2+-sensitivity probably by increasing the permeability of the inner membrane.UniRule annotation3 Publications

Part of a complex composed of FtsB, FtsL and FtsQ. The complex can be formed before its localization to the division site. This tripartite complex can be divided further into a subcomplex of FtsB and FtsL, which forms in the absence of FtsQ.

Interacts also with FtsI, FtsN and YmgF. Homodimer in vitro. May form multimers.

The cytoplasmic region is involved in recruitment of the downstream cell division protein FtsW. The transmembrane segment and the membrane-proximal periplasmic region form a coiled-coil structure and are required for septal localization and interaction with FtsB. The C-terminal region is required for interaction with FtsQ. Contains a leucine zipper-like (LZ) motif, which is required for optimal interaction with FtsB.2 Publications

<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:i6DD5DF7B2ECB7090
