Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a mechanism in which water acts as a nucleophile, one or two metal ions hold the water molecule in place, and charged amino acid side chains are ligands for the metal ions.

Metalloproteinase-disintegrins (ADAMs) are type 1 transmembrane proteins that contain a unique domain structure including a zinc-binding metalloproteinase domain. We have isolated cDNAs encoding two novel members of this family, ADAM29 and ADAM30 which show testis-specific expression. Three forms of ADAM29 were found that encode proteins of 820, 786 and 767 amino acids. All of the amino acid differences are located in the cytoplasmic domain. Two forms of ADAM30 were isolated that encode proteins of 790 and 781 amino acids, with the difference in the coding region occurring in the cytoplasmic domain. ADAM29 and ADAM30 map to human chromosome 4q34 and 1p11-13, respectively. An ancestral analysis of all known mammalian ADAMs indicates that the zinc-binding motif in the catalytic domain arose once in a common ancestor and was subsequently lost by those members lacking this motif.

A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
