PF00240Ubiquitin family (ubiquitin)Ubiquitin familyThis family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260).

A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].

PF00899ThiF family (ThiF)ThiF familyThis domain is found in ubiquitin activating E1 family and members of the bacterial ThiF/MoeB/HesA family. It is repeated in Ubiquitin-activating enzyme E1 [1-3]. Domain
PF09358Ubiquitin fold domain (E1_UFD)Ubiquitin fold domainThe ubiquitin fold domain is found at the C-terminus of ubiquitin-activating E1 family enzymes. This domain binds to E2 enzymes [1]. Domain
PF10585Ubiquitin-activating enzyme, SCCH domain (UBA_E1_SCCH)Ubiquitin-activating enzyme, SCCH domainUbiquitin-activating enzyme (E1 enzyme) 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 A ...Ubiquitin-activating enzyme (E1 enzyme) 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) [1]. This domain carries the last of five conserved cysteines that is part of the active site of the enzyme, responsible for ubiquitin thiolester complex formation, the active site being represented by the sequence motif PICTLKNFP [2,3,4]. The catalytic cysteine domain contains the E1 active site cysteine, and is divided in two half-domains, FCCH and SCCH, for 'first' and 'second' catalytic cysteine half-domain, respectively. This is the SCCH domain in which resides the catalytic cysteine [5].

Ubiquitination follows conjugation of ubiquitin to a conserved cysteine residue of UBC homologues. TSG101 is one of several UBC homologues that lacks this active site cysteine [4, 5].
