== Function ==

[https://www.uniprot.org/uniprot/ATXE2_ASTEC ATXE2_ASTEC] Lasso peptide isopeptidase that specifically hydrolyzes Astexin-2 and Astexin-3, converting them to linear peptides (PubMed:23862624). Has only a few specific contacts with subrates, because it recognizes Astexin knotted structure (principally the loop structure) (PubMed:26534965, PubMed:27998080). Its binding to lasso peptides opens them to expose the isopeptide bonds for hydrolysis (PubMed:27998080).<ref>PMID:23862624</ref> <ref>PMID:26534965</ref> <ref>PMID:27998080</ref>
