Recovery of the recombinant protein from the host system needs to be devised and established, since the conventional downstream process for recombinant protein extraction is associated with high costs and resources. In a previous study, we have reported two putative signal peptides of C. aponinum using in silico approach. Herein, we evaluated the two secretory signal peptides for heterologous protein secretion in C. aponinum PCC10605. The green fluorescent protein was used as secretory protein and as a reporter. Signal peptides, thermitase and porin, fused with GFP were transformed in to C. aponinum for studying the expression and secretion. Following the antibiotic screening and GFP fluorescence analysis, transformants secreting GFP in the supernatant were validated by using western blotting. The results showed that fluorescence, as measured by FACS analysis and TECAN reader, varied among the two signal peptides and, higher fluorescence was recorded in the 'thermitase SP secreted GFP' supernatant.

In the last decades, mushroom tyrosinase was used as a standard enzyme for the identification and advancement of most tyrosinase inhibitors. Due to differences in structure and substrate specificity between mushroom and human tyrosinase, there is a need for a more specific study with human tyrosinase. Additionally, the tyrosinase inhibitors which are currently in use have various side effects, therefore, safer inhibitors from natural sources are required. Different tyrosinase inhibitors from natural sources (aloesin, norartocarpetin, hesperetin, morin and taxifolin) were evaluated for an effective eco-friendly whitening agent using different bioinformatics tools. To check the efficacy and safety of the selected compounds ADME analysis was performed which showed that all the selected compounds fulfilled most of the parameters of general drug discovery. Docking of selected ligands was performed against the predicted structure of human tyrosinase; and the binding affinity (in kcal/mol) of kojic acid, aloesin, norartocarpetin, hesperetin, morin and taxifolin were obtained to be - 5.6, - 7.2, - 7.6, - 7.5, - 7.3 and - 7.2 respectively. Among all the selected ligands, norartocarpetin had the lowest binding affinity, i.e., - 7.6 kcal/mol, which showed that norartocarpetin could be used as a potent tyrosinase inhibitor.
