Combined analysis of the MEROPS database (https://www.ebi.ac.uk/merops/), several published papers (FBrf0224452, FBrf0214506, FBrf0204608, FBrf0134455) and InterPro annotations (Peptidase M13 family", IPR000718) in FlyBase identifies a total of 28 D. melanogaster genes encoding M13 class metalloendopeptidases.  7 of these contain all four of the conserved motifs identified as important for catalytic activity in vertebrate neprilysins - these are classed as 'Neprilysins' and given a 'Nep' prefix, and include the previously named genes Nep1, Nep2, Nep3, Nep4 and Nep5. The other 21 genes encode proteins with significant similarity to Neprilysins but lack one of more of the catalytically important motifs - these may be catalytically inactive, and are classed as 'Neprilysin-like' and given a 'Nepl' prefix. The names of 'frma' (CG3239) and 'goe' (CG9634) have not been changed, but 'Nepl1' and 'Nepl2' are added as respective synonyms to recognize the fact they were the first and second Nep-like genes to be characterized. The remaining Nepl genes are given a numerical suffix, incremented based on their genomic location. See associated files for additional information and analysis.
