ThiF_MoeB_HesA. Family of E1-like enzymes involved in molybdopterin and thiamine biosynthesis family. The common reaction mechanism catalyzed by MoeB and ThiF, like other E1 enzymes, begins with a nucleophilic attack of the C-terminal carboxylate of MoaD and ThiS, respectively, on the alpha-phosphate of an ATP molecule bound at the active site of the activating enzymes, leading to the formation of a high-energy acyladenylate intermediate and subsequently to the formation of a thiocarboxylate at the C termini of MoaD and ThiS. MoeB, as the MPT synthase (MoaE/MoaD complex) sulfurase, is involved in the biosynthesis of the molybdenum cofactor, a derivative of the tricyclic pterin, molybdopterin (MPT). ThiF catalyzes the adenylation of ThiS, as part of the biosynthesis pathway of thiamin pyrophosphate (vitamin B1). Pssm-ID: 238386 [Multi-domain] Cd Length: 228 Bit Score: 293.61 E-value: 3.94e-101

Ubiquitin activating enzyme (E1) subunit UBA2. UBA2 is part of the heterodimeric activating enzyme (E1), specific for the SUMO family of ubiquitin-like proteins (Ubls). E1 enzymes are part of a conjugation cascade to attach Ub or Ubls, covalently to substrate proteins consisting of activating (E1), conjugating (E2), and/or ligating (E3) enzymes. E1 activates ubiquitin by C-terminal adenylation, and subsequently forms a highly reactive thioester bond between its catalytic cysteine and Ubls C-terminus. The E1 also associates with E2 and promotes ubiquitin transfer to the E2's catalytic cysteine. Post-translational modification by SUMO family of ubiquitin-like proteins (Ublps) is involved in cell division, nuclear transport, the stress response and signal transduction. UBA2 contains both the nucleotide-binding motif involved in adenylation and the catalytic cysteine involved in the thioester intermediate and Ublp transfer to E2.

ABPP1 contains part of the adenylation domain. Pssm-ID: 238770 [Multi-domain] Cd Length: 425 Bit Score: 60.01 E-value: 2.40e-10

Apg7 is an E1-like protein, that activates two different ubiquitin-like proteins, Apg12 and Apg8, and assigns them to specific E2 enzymes, Apg10 and Apg3, respectively. This leads to the covalent conjugation of Apg8 with phosphatidylethanolamine, an important step in autophagy. Autophagy is a dynamic membrane phenomenon for bulk protein degradation in the lysosome/vacuole. Pssm-ID: 238763 [Multi-domain] Cd Length: 307 Bit Score: 58.54 E-value: 5.45e-10

E1-like protein-activating enzyme Gsa7p/Apg7p; This model represents a family of eukaryotic proteins found in animals, plants, and yeasts, including Apg7p (YHR171W) from Saccharomyces cerevisiae and GSA7 from Pichia pastoris. Members are about 650 to 700 residues in length and include a central domain of about 150 residues shared with the ThiF/MoeB/HesA family of proteins. A low level of similarity to ubiquitin-activating enzyme E1 is described in a paper on peroxisome autophagy mediated by GSA7, and is the basis of the name ubiquitin activating enzyme E1-like protein. Members of the family appear to be involved in protein lipidation events analogous to ubiquitination and required for membrane fusion events during autophagy.

bacteriocin biosynthesis cyclodehydratase domain; This model describes a ThiF-like domain of a fusion protein found in clusters associated with the production of TOMMs (thiazole/oxazole-modified microcins), small bacteriocins with characteristic heterocycle modifications. This domain is presumed to act as a cyclodehydratase, as do members of the SagC family modeled by TIGR03603. Pssm-ID: 274832 Cd Length: 164 Bit Score: 39.26 E-value: 6.66e-04
