HHsearch alignment for GI: 254781166 and conserved domain: cd01484

>cd01484 E1-2_like Ubiquitin activating enzyme (E1), repeat 2-like. E1, a highly conserved small protein present universally in eukaryotic cells, is part of cascade to attach ubiquitin (Ub) covalently to substrate proteins. This cascade consists of activating (E1), conjugating (E2), and/or ligating (E3) enzymes and then targets them for degradation by the 26S proteasome. E1 activates ubiquitin by C-terminal adenylation, and subsequently forms a highly reactive thioester bond between its catalytic cysteine and ubiquitin's C-terminus. E1 also associates with E2 and promotes ubiquitin transfer to the E2's catalytic cysteine. A set of novel molecules with a structural similarity to Ub, called Ub-like proteins (Ubls), have similar conjugation cascades. In contrast to ubiquitin-E1, which is a single-chain protein with a weakly conserved two-fold repeat, many of the Ubls-E1are a heterodimer where each subunit corresponds to one half of a single-chain E1. This CD represents the family homologou
