Antimicrobial resistance is a serious worldwide threat to public health that is emerging due to de misuse and overuse of antimicrobials. In fact, infectious diseases are the second most frequent cause of death worldwide. Thus, it is of foremost importance to discover new therapeutic approaches against microbial pathogens. Antimicrobial peptides (AMPs) are promising alternatives to classical antimicrobials, especially because the acquisition of resistance to AMPs is significantly reduced. In general, extraction of these peptides from natural sources or by chemical synthesis is a cumbersome, complex and expensive process that does not provide an efficient method to obtain peptides in large amounts. One way to potentially overcome these drawbacks is by exploring the use of recombinant DNA technology for the biotechnological production of AMPs using microbial cell factories. Nevertheless, due to their nature, AMPs are usually expressed in insoluble inclusion bodies and are susceptible to proteolysis. The use of recombinant protein-based polymers (rPBPs) that act as polymer fusion partners presents several advantages: increases the solubility of the AMPs; function as purification tag and allows the creation of functionalized antimicrobial biomaterials. Owing to the unique balance between their mechanical properties, biocompatibility, biodegradability and thermostability, elastin-like recombinamers (ELRs) and silk-elastin like proteins (SELPs) are two of the most remarkable families of rPBPs for biotechnological applications, particularly for the biomedical field.
