Lysin-antimicrobial peptide (AMP) polypeptide constructs, lysins, isolated polynucleotides encoding same and uses thereof

Abstract:

The present disclosure is directed to a lysin-AMP polypeptide construct comprising: (a) a first component comprising the polypeptide sequence of: (i) SEQ ID NO: 118 (GN202); or (ii) a polypeptide having lysin activity and having at least 80% sequence identity with the polypeptide sequence of SEQ ID NO: 118 (GN202); or (iii) an active fragment of SEQ ID NO: 118 (GN202); and (b) a second component comprising the polypeptide sequence of at least one antimicrobial peptide (AMP), wherein the at least one AMP comprises SEQ ID NO: 114 (FIRL). Exemplary lysin-AMP polypeptides, such as GN370 (SEQ ID NO: 44) as well as methods of treating bacterial infections using the present lysin-AMP polypeptide constructs are also disclosed.
