A C39-like protein from methanogenic archaea: structural insights and functional divergence in β-galactose analogue degradation
Methanogenic archaea harbor diverse enzymes that support their survival in extreme environments and play key roles in global carbon cycling. The C39 peptidase family, known for cleaving peptide substrates, now gains functional expansion through A0A126R2S0, a novel enzyme that shares structural homology with C39 peptida...
