WAM-1 antimicrobial peptide from the tammar wallaby (Macropus eugenii)

An antimicrobial peptide from the cathelicidin family of peptides, isolated from the tammar wallaby (Macropus eugenii). WAM-1 is one of several identified peptides that are produced in the mammary gland throughout lactation in order to supply protection from infection to the young wallabies that have underdeveloped immune systems. This is evident through the down-regulation of these peptides in the tammar wallaby milk at around 100 days after birth, the same period that the wallaby young develop immunocompetence (Wang, et. al 2011).

Similar to other members of the cathelicidin family, the WAM-1 antimicrobial peptide has been shown to be effective against a broad range of bacterial pathogens (Kastin, A. J. 2013). Specifically, a group of researchers from Australia (Wang, et. al 2011) have tested this peptide, isolated from its natural source, against several gram-negative (E. coli, P. aeruginosa, among others) and gram-positive (B. subtilis, S. aureus, among others) bacterium with minimum inhibitory concentration (MIC) values that indicate highly effective antibiotic activity. To our knowledge, this antimicrobial peptide has not been previously expressed or purified recombinantly in E. coli.
