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 54 members:Aspzincin_M35 Astacin BSP DUF1570 DUF2201_N DUF2268 DUF3152 DUF3633 DUF3810 DUF4157 DUF45 DUF955 Enhancin HRXXH M60-like Peptidase_M1 Peptidase_M10 Peptidase_M11 Peptidase_M13 Peptidase_M2 Peptidase_M27 Peptidase_M3 Peptidase_M30 Peptidase_M32 Peptidase_M35 Peptidase_M36 Peptidase_M4 Peptidase_M41 Peptidase_M43 Peptidase_M48 Peptidase_M4_C Peptidase_M50 Peptidase_M50B Peptidase_M54 Peptidase_M56 Peptidase_M57 Peptidase_M6 Peptidase_M61 Peptidase_M64 Peptidase_M66 Peptidase_M7 Peptidase_M8 Peptidase_M9 Peptidase_M91 Peptidase_MA_2 Peptidase_U49 Reprolysin Reprolysin_2 Reprolysin_3 Reprolysin_4 Reprolysin_5 SprT-like WLM Zn_peptidase
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

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 Reprolysin_2 domain has been found. There are 11 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.
