Summary: Peptidase M30
Pfam includes annotations and additional family information from a range of different sources. These sources can be accessed via the tabs below.
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.
This tab holds the annotation information that is stored in the Pfam database. As we move to using Wikipedia as our main source of annotation, the contents of this tab will be gradually replaced by the Wikipedia tab.
Peptidase M30 Provide feedback
This family contains the metallopeptidase hyicolysin. Hyicolysin has a zinc ion which is liganded by two histidine and one glutamate residue.
This tab holds annotation information from the InterPro database.
InterPro entry IPR019501
Over 70 metallopeptidase families have been identified to date. In these enzymes a divalent cation which is usually zinc, but may be cobalt, manganese or copper, activates the water molecule. The metal ion is held in place by amino acid ligands, usually three in number. In some families of co-catalytic metallopeptidases, two metal ions are observed in crystal structures ligated by five amino acids, with one amino acid ligating both metal ions. The known metal ligands are His, Glu, Asp or Lys. At least one other residue is required for catalysis, which may play an electrophillic role. Many metalloproteases contain an HEXXH motif, which has been shown in crystallographic studies to form part of the metal-binding site [ PUBMED:7674922 ]. The HEXXH motif is relatively common, but can be more stringently defined for metalloproteases as 'abXHEbbHbc', where 'a' is most often valine or threonine and forms part of the S1' subsite in thermolysin and neprilysin, 'b' is an uncharged residue, and 'c' a hydrophobic residue. Proline is never found in this site, possibly because it would break the helical structure adopted by this motif in metalloproteases [ PUBMED:7674922 ].
This family contains metallopeptidases belonging to MEROPS peptidase family M30 (hyicolysin family, clan MA). Hyicolysin (ShpI) is a neutral metalloprotease from Staphylococcus hyicus [ PUBMED:8195076 ] It has a zinc ion which is liganded by two histidine and one glutamate residue.

Pfam Clan
This family is a member of clan Peptidase_MA (CL0126), which has the following description:
Clan MA is one of two zinc-dependent metallopeptidases that contain the HEXXH motif. The two histidines are zinc ligands. The structures of this clan show the active site is between its two sub-domains.
The clan contains the following 74 members:

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets and the UniProtKB sequence database. More...

We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

HMM logos is one way of visualising profile HMMs. Logos provide a quick overview of the properties of an HMM in a graphical form. You can see a more detailed description of HMM logos and find out how you can interpret them here. More...
Trees
This page displays the phylogenetic tree for this family's seed alignment. We use FastTree to calculate neighbour join trees with a local bootstrap based on 100 resamples (shown next to the tree nodes). FastTree calculates approximately-maximum-likelihood phylogenetic trees from our seed alignment.
Note: You can also download the data file for the tree.
