Abstract:Biochemical and structural analyses of purified proteins are essential for the understanding of their properties. However, many proteins are unstable and difficult to purify, hindering their characterization. The B2 proteins of the lasso peptide biosynthetic pathways are cysteine proteases that cleave precursor peptides during the maturation process. The B2 proteins are poorly soluble and no experimentally-solved structures are available. Here, we performed a rabid semi-comprehensive mutational analysis of the… Show more
