This entry represents the so-called Rider domain of K1 capsule-specific polysaccharide lyase and related proteins. K1-lyase functions as a receptor binding protein (RBP) and mediates the attachment to the host capsular exopolysaccharides [1]. This enzyme possesses a lyase activity that specifically degrades the K1-type polysaccharides of Klebsiella pneumoniae capsule [1]. The Rider domain folds into a beta-barrel, participates in polysaccharide binding to both carbohydrate-binding sites of the enzyme and makes an important contribution to the structural stability of the trimeric K1-lyase [1].
