Sulfatase-modifying factor enzyme 1; This domain is found in eukaryotic proteins required for post-translational sulfatase modification (SUMF1). These proteins are associated with the rare disorder multiple sulfatase deficiency (MSD). The protein product of the SUMF1 gene is FGE, formylglycine (FGly),-generating enzyme, which is a sulfatase. Sulfatases are enzymes essential for degradation and remodelling of sulfate esters, and formylglycine (FGly), the key catalytic in the active site, is unique to sulfatases. FGE is localized to the endoplasmic reticulum (ER) and interacts with and modifies the unfolded form of newly synthesized sulfatases. FGE is a single-domain monomer with a surprising paucity of secondary structure that adopts a unique fold which is stabilized by two Ca2+ ions. The effect of all mutations found in MSD patients is explained by the FGE structure, providing a molecular basis for MSD. A redox-active disulfide bond is present in the active site of FGE. An oxidized cysteine residue, possibly cysteine sulfenic acid, has been detected that may allow formulation of a structure-based mechanism for FGly formation from cysteine residues in all sulfatases. In Mycobacteria and Treponema denticola this enzyme functions as an iron(II)-dependent oxidoreductase.

Characterized homologs to this family include a formylglycine-generating enzyme that serves as a maturase for an aerobic sulfatase (cf. the radical SAM enzymes that serve as anaerobic sulfatase maturases).

selenoneine synthase SenA; Selenoneine is the selenium analog of ergothioneine, a sulfur-containing derivative of a hercynine, which derives from histidine by trimethylation of its amino group. SenA, a homolog of ergothioneine biosynthesis protein EgtB, completes selenoneine biosynthesis in a pathway that also requires a SelD protein to prepare selenophosphate, EgtD to prepare hercynine, and the selenosugar-producing glycosyltransferase SenB (TIGR04348). SenA catalyzes selenium-carbon bond formation between hercynine and selenosugar to produce selenoneine. Other enzymes that create carbon-selenium bonds include SelA, involved in selenocysteine biosynthesis, SelU, involved in selenouridine biosynthesis, and SbtM, a radical SAM enzyme involved in post-translational modification of the RiPP precursor SbtA (see PMID:34730336).

gliding motility-associated lipoprotein GldK; Members of this protein family are exclusive to the Bacteroidetes phylum (previously Cytophaga-Flavobacteria-Bacteroides). GldK is a lipoprotein linked to a type of rapid surface gliding motility found in certain Bacteroidetes, such as Flavobacterium johnsoniae. Knockouts of GldK abolish the gliding phenotype. GldK is homologous to GldJ. There is a GldK homolog in Cytophaga hutchinsonii and several other species that has a different, shorter architecture and is represented by a separate model. Gliding motility appears closely linked to chitin utilization in the model species Flavobacterium johnsoniae. Bacteroidetes with members of this protein family appear to have all of the genes associated with gliding motility.
