Provided are polypeptides that have at least about 95% but less than 100% sequence identity to SEQ ID NO: 2, optionally wherein the polypeptide has an amino acid sequence as set forth in SEQ ID NO: 4, with the proviso that the polypeptide does not have 100% sequence identity to SEQ ID NO: 2. Also provided are polypeptides that include an amino acid sequence that is a variant of SEQ ID NO: 2, wherein the variant sequence has at least one substitution at an amino acid position selected from the group consisting of D287, D291, D311, N313, D315, L307, and N284 of SEQ ID NO: 2; optionally wherein the polypeptide inhibits growth of a microbe and/or microbial biofilm and/or disrupts a microbial biofilm; nucleic acid molecules encoding the disclosed polypeptides; vectors and recombinant host cells that include the disclosed nucleic acid molecules; antimicrobial compositions that include an effective amount of the disclosed polypeptides, optionally that also include a carrier and/or one or more additional active agents; and methods for inhibiting the growth of microbes and/or microbial biofilms on surfaces and/or for disrupting microbial biofilms on surfaces and methods for inhibiting the growth of microbes on and/or in agricultural products and/or subjects.
