Protein from Methanobacterium thermoautotrophicam

ID Number
2374

Description
A knotted protein from an archaebacterium called Methanobacterium thermoautotrophicam. This organism breaks down waste products and produces methane gas. Protein folding theory previously held that forming a knot was beyond the ability of a protein, but this structure, determined at Argonne's Structural Biology Center, proves differently. Researchers theorize that this knot stabilizes the amino acid subunits of the protein.
