Parseq-α

Parseq alpha is a de novo antimicrobial peptide. It was generated by the Parseq model and the antimicrobial activity was predicted by the Parseq model. This part was designed to be assembled with BBa_K3182010. This part was first ordered chemically synthesised by Caslo to investigate its antimicrobial activity on its own. The peptides were dissolved in 6 M Urea due to their hydrophobic nature. The activity was tested on E.coli and B.Subtilis. The antimicrobial activity assay was carried out in a 96 well plate. Bacteria were combined with the antimicrobial peptides in different concentrations. They were then incubated at 37°C, with shaking, every 15 minutes. The plate was incubated for 16 hours and OD⁶⁰⁰ was measured. The results can be seen in Figure 1.. Parseq alpha showed an inhibiting effect on the growth of E.coli. A concentration of 30 ng/mL completely inhibited the growth of E.coli. B.subtilis could not be inhibited completely by Parseq Alpha. However, high concentrations of the peptide showed partial inhibition of the growth of B.subtilis.

Figure 1 Shows the antimicrobial activity of Parseq Alpha on A) E.Coli. and B) B.subtilis. The samples were cultured in 200 µL, in a 96 well plate and incubated at 37°C. Shaking was conducted for 1 minute every 15 minutes and the OD⁶⁰⁰ was measured every hour for 16 hours. The negative control represents the bacterial growth with no antimicrobial peptides present. All measurements are done in 6 replicates and error bars represent SD. The graphs were created in Graphpad
