Tail tubular protein A

UniProtKB accession:  D1L2W4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Structural component of the tail, which functions as a receptor binding protein (RBP) and mediates the attachment to the host capsular exopolysaccharides (PubMed:28533535). Displays a depolymerase activity that specifically degrades the polysaccharides of Klebsiella pneumoniae capsule, which allows the phage to reach the host cell membrane and bind the entry receptor (PubMed:28533535). Hydrolyzes maltose (PubMed:29273737). Does not hydrolyze alpha-lactose, beta-lactose, trehalose, melibiose, cellobiose (PubMed:29273737). Displays amylase activity (PubMed:29273737).
