    📢 Just published! Introducing Isopeptor: a computational tool for detecting intramolecular isopeptide bonds in protein structures with high precision and recall.
    PDB depositions of intramolecular isopeptide bond domain structures over the years. Isopeptide bonds were not modeled into deposited structures until 2007, after Kang et al.’s discovery of intramolecular isopeptide bonds (Kang et al. 2007). A number of intramolecular isopeptide bond domain structures have been deposited without a modeled intramolecular isopeptide bond, or with bond geometries that do not fit the...

    Check out this article about my research at @emblebi where I focus on protein modelling and on the study of fibrillar adhesins. Recently, we developed a method to detect isopeptide bonds, a key stabilizing feature in bacterial proteins. Big thanks to @oanastroe123!!👇

    Excited to announce our latest publication: “Keeping it in the family: Using protein family templates to rescue low confidence AlphaFold2 models” where we explore plDDT variability in #AF2 models of @PfamDB domains. doi.org/10.1093/bioadv… 1/7
    Distributions of the mean plDDT values taken from AFDB models for protein domains from Pfam families (A) Big_1 PF02369 and (B) family Trp_oprn_chp PF09534. Note that the mean plDDT values here are not for the whole protein length but rather the domain extent (grey regions are excluded). (C) Examples of AlphaFold2 models for family PF09534: low domain plDDT, UniProtKB: A0A426UPE9 and high domain plDDT, UniProtKB:...

    Feature 932 appears to associate with Asn involved in isopeptide bonds. Very cool work! (PDB IDs: 4OFQ, 2OKM, 1AMX)

    Replying to @liambai21
    Nonetheless, we’re excited to have deciphered (to some extent) the missing cysteine feature. But we have so many questions… If you’re interested in playing around with our SAE features, they’re all available at interprot.com.
