Figure 2From: Characterization of a new oxidant-stable serine protease isolated by functional metagenomics Sequence alignment between SBcas3.3 and the KP-43 peptidase of Bacillus sp. strain KSM-KP43 (BAB55674). Conserved residues are shaded in grey. Asterisks: conserved catalytic residues. The vertical bar indicates separation between the preprodomain of KP-43 and its catalytic domain released after autocatalytic cleavage.Back to article page
