Summary: SMP-30/Gluconolaconase/LRE-like region
The Pfam group coordinates the annotation of Pfam families in Wikipedia, but we have not yet assigned a Wikipedia article to this family. If you think that a particular Wikipedia article provides good annotation, please let us know.
SMP-30/Gluconolaconase/LRE-like region Provide feedback
This family describes a region that is found in proteins expressed by a variety of eukaryotic and prokaryotic species. These proteins include various enzymes, such as senescence marker protein 30 (SMP-30, Q15493), gluconolactonase (Q01578) and luciferin-regenerating enzyme (LRE, Q86DU5). SMP-30 is known to hydrolyse diisopropyl phosphorofluoridate in the liver, and has been noted as having sequence similarity, in the region described in this family, with PON1 (P52430) and LRE .

This large clan contains proteins that contain beta propellers. These are composed of between 6 and 8 repeats. The individual repeats are composed of a four stranded sheet. The clan includes families such as WD40 Pfam:PF00400 where the individual repeats are modeled. The clan also includes families where the entire propeller is modeled such as Pfam:PF02239 usually because the individual repeats are not discernible. These proteins carry out a very wide diversity of functions including catalysis.
The clan contains the following 67 members:ANAPC4_WD40 Arylesterase Arylsulfotran_2 Arylsulfotrans BBS2_Mid Beta_propel Coatomer_WDAD CPSF_A Cytochrom_D1 DPPIV_N DUF1513 DUF1668 DUF2415 DUF3312 DUF4221 DUF5050 DUF839 eIF2A FG-GAP FG-GAP_2 Ge1_WD40 Glu_cyclase_2 Gmad1 GSDH IKI3 Itfg2 Kelch_1 Kelch_2 Kelch_3 Kelch_4 Kelch_5 Kelch_6 Lactonase Ldl_recept_b Lgl_C LVIVD Me-amine-dh_H MRJP Nbas_N Neisseria_PilC NHL Nucleoporin_N Nup160 PALB2_WD40 PD40 Pectate_lyase22 Peptidase_S9_N Phytase-like PQQ PQQ_2 PQQ_3 RAG2 RCC1 RCC1_2 Reg_prop SBBP SBP56 SdiA-regulated SGL Str_synth TcdB_toxin_midN TolB_like VCBS WD40 WD40_3 WD40_4 WD40_like
We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request

- show/hide the summary boxes
- highlight species that are represented in the seed alignment
- expand/collapse the tree or expand it to a given depth
- select a sub-tree or a set of species within the tree and view them graphically or as an alignment

There is 1 interaction for this family. More...
We determine these interactions using iPfam, which considers the interactions between residues in three-dimensional protein structures and maps those interactions back to Pfam families. You can find more information about the iPfam algorithm in the journal article that accompanies the website.
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the SGL domain has been found. There are 82 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein seqence.
