Metal‐Coordination Specificity and Structural Dynamics of C. elegans Metallothionein I: Insights From 3D Modeling and MD Simulations

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 2, Page 620-632, February 2026.
ABSTRACT Metallothioneins (MTLs) are small, cysteine‐rich proteins known for their ability to bind metal ions and exhibit flexible, disordered structures. The structural and functional characteristics of metallothionein I (MTL‐1) from Caenorhabditis elegans were investigated, focusing on its behavior in both metal free (MTL‐1 Apo) and metal‐bond states
