Experimental validation

Validated by sequence identity

The evidence was produced on a different entry with an identical sequence. Strong, but the experiment was not done on this protein.

 ECO:0000269:FUNCTION:28077636 RBP Functions as a receptor binding protein (RBP) and probably mediates the attachment to the host capsular exopolysaccharides (Probable). Displays a depolymerase activity that specifically degrades the KN4-type polysaccharides of Klebsiella pneumoniae capsule (PubMed:28077636) PMID 28077636

Rows marked “Validated by sequence identity” come from a different entry carrying the same sequence — the experiment was not performed on this protein.
