Additional Information

Clan 5 also holds families of isoaspartyl peptidases.

Family 14 contains the quintessential type III l‑asparaginases (or l‑asparaginase-like proteins) from plants: the Lupinus luteus LlAIII (Q9ZSD6) and the Phaseolus vulgaris PvAIII (V7CU13), but interestingly also the cytoplasmic Escherichia coli EcAIII (P37595). Protein structures have been solved for all three of these. Aside from plant and bacterial enzymes, this family also holds enzymes of fungal origin
