Annotation score:5 out of 5

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

A 50S ribosomal subunit assembly protein with GTPase activity, required for 50S subunit assembly at low temperatures, may also play a role in translation. Binds GTP and analogs. Binds the 70S ribosome between the 30S and 50S subunits, in a similar position as ribosome-bound EF-G; it contacts a number of ribosomal proteins, both rRNAs and the A-site tRNA (By similarity).

GTPase that impacts interactions between enteropathogenic E.coli (EPEC) and epithelial cells and also has an effect on motility (PubMed:9622352).

Deletion alters the pattern of protein synthesis during both exponential growth and carbon starvation (PubMed:9642082). No longer alters host cytoskeleton; upon infection of HeLa cells microvilli are not disrupted (although some thicken), bacteria adhere to host cells but actin does not accumulate beneath them. 100-fold increased sensitivity of bacteria to human BPI. Increased bacterial cell motililty, increased secretion of flagellin gene (fliC) (PubMed:9622352). Decreased accumulation in infected HeLa cells of a phosphotyrosine protein that might be bacterial Tir, enhanced Ca2+ efflux from infected HeLa cells (PubMed:9765944).3 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.
