IPR018074 is a Ubiquitin-activating enzyme E1, conserved site.
<p>Ubiquitin-activating enzyme (E1 enzyme) [[cite:PUB00000623], [cite:PUB00005373]] activates ubiquitin by first adenylating with ATP its C-terminal glycine residue and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding an ubiquitin-E1 thiolester and free AMP. Later the ubiquitin moiety is transferred to a cysteine residue on one of the many forms of ubiquitin- conjugating enzymes (E2).</p> <p>E1 is a large monomeric protein of about 110 to 115 Kd (about 1000 residues). In yeast there are two forms (UBA1 and UBA2) [[cite:PUB00002915]], while in plants and mammals multiple forms exist including a form which is Y-linked in mouse and some other mammals and which may be involved in spermatogenesis.</p> <p>It has been shown that the last of the five cysteines that are conserved in the sequence of E1 from various species is the one that binds ubiquitin [[cite:PUB00002725]]. This entry represents a conserved region containing the second of the five conserved cysteines.</p>
