Microorganisms may 12926553 cause enormous problems in diverse fields, including human health and agribusiness. In the last few decades, many microorganisms have developed resistance against a number of antimicrobial agents. In this context, the antimicrobial peptides (AMP) have been proposed as an alternative to control such dangerous microorganisms [1]. The AMPs can perform different functions under different environmental conditions. This ability is also known as ‘peptide promiscuity’ [2]. According to Franco (2011) [2], there are two levels of multifunctionality, where on the first level, a single peptide can perform diverse functions; and on the second level, a peptide superfamily has members with different functions and/or members with multiple activities, which could be related to different exposed residues in the same structural framework [2]. These compounds have been isolated from several sources, in all life kingdoms [1,3], and they can be classified in two major groups, according to the presence or absence of disulphide bridges [3]. The disulphide-free peptides are composed mainly of a-helical and unstructured AMPs; while the cysteine-stabilized AMPs are composed of several classes, which are divided according to their disulphide patterns. The cysteine-stabilized peptides can be related to both multifunctional behaviors [2,4], with a 
strong tendency to have superfamily multifunctionality. Family’s multifunctional behavior has been linked to special events, such as gene duplication, which allow the generation of novel protein functions derived from the ability of a protein toadopt a new function based on the modification of a few amino acid residues in an 115103-85-0 existing fold [2,5]. Those modifications can have effects, 
slight or not, on the pivotal function, being able to yield a totally 1516647 unusual function. Therefore, the structure-activity relationship is controversial for AMPs, since this relationship is becoming more and more unclear [2]. This kind of behavior can be observed in several cysteinestabilized peptides, including the ones which are restricted to one life kingdom, such as the a defensins from vertebrates [6,7]; the cyclotides [8,9] and the thionins [10,11] from plants; and also observed in classes which can be found in more than one life kingdom, such as the CSab defensins, which can be found in plants [12,13], insects [14,15] and fungi [16,17,18]; and the hevein-like peptides, which can be found in plants and fungi [4,19]. Recently, it has been proposed that physicochemical properties can be used as descriptors to predict the antimicrobial activity of cysteine-stabilized peptides by means of machine learning methods [20]. Several studies have applied machine learning methods for antimicrobial activity prediction [20?6]. These methods aim to identify AMPs prior to in vitro tests, so that antim.Hen rates of fatty acid oxidation are high.
