Annotation score:3 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>

Required for the polymorphic O-glycosylation of the serine-rich repeat protein PsrP. A stabilizing protein that is part of the accessory SecA2/SecY2 system specifically required to export serine-rich repeat cell wall proteins encoded upstream in the same operon. The GtfA-GtfB complex adds GlcNAc from UDP-GlcNAc to PsrP, attaching the first sugar residue. Stabilizes the glycosylation activity of GtfA (By similarity) (PubMed:24936067, PubMed:28246170). Has no N-acetylglucosaminyl transferase activity on its own (PubMed:24936067).UniRule annotation2 Publications

Miscellaneous

Encoded in RD10, a pathogenicity island with an atypical GC content that is associated with invasive pneumococcal disease. Pathogenicity islands account for greater than half the genomic diversity observed between isolates (PubMed:11463916, PubMed:16861665). The main function of this island seems to be correct synthesis and export of pneumococcal serine-rich repeat protein PsrP (Probable).2 PublicationsCurated

The N-terminus of the protein, including the glycosyltransferase 1 domain (residues 1-171), is required but not sufficient for full formation of the stable GtfA-GtfB complex; the complex of GtfA with truncated GtfB has intermediate N-acetylglucosaminyl transferase activity.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. 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:i8A2E2DD880CFD53C
