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

The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane. The enzyme II complex composed of PtsG and Crr is involved in glucose transport (PubMed:6754734, PubMed:6292227).

It can also phosphorylate mannose, methyl alpha-glucoside and 2-deoxy-glucose (PubMed:6292227).

The non-phosphorylated EIII-Glc is an inhibitor for uptake of certain sugars such as maltose, melibiose, lactose, and glycerol. Phosphorylated EIII-Glc, however, may be an activator for adenylate cyclase (PubMed:789369).

Miscellaneous

Two forms of III-Glc (called IIIGlc Slow and IIIGlc Fast) are present in living cells. IIIGlc Fast, derived from IIIGlc Slow by cleavage of the seven NH2-terminal amino acids, is present only in trace quantities and has slight activity (only 2-3% of phospho-IIIGlc Slow) in the phosphorylation of sugar. Both forms accept phosphate from phosphoenolpyruvate via Enzyme I and HPr, however only IIIGlc Slow participates in the phosphorylation of glucose or methyl alpha-D-glucoside. IIIGlc Fast may play a role in the regulation of non-PTS sugar transport systems.1 Publication

<p>This subsection of the 'Function' section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

<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.
