Our novel strategy for the rational design of immobilized derivatives (RDID) is directed to predict the behavior of the protein immobilized derivative before its synthesis, by the usage of mathematic algorithms and bioinformatics tools. However, this approach needs to be validated for each target enzyme. The objective of this work was to validate the RDID strategy for covalent immobilization of the enzyme laccase from Trametes maxima MUCL 44155 on glyoxyl‐ and monoaminoethyl‐N‐aminoethyl (MANA)‐Sepharose CL 4B supports. Protein surface clusters, more probable configurations of the protein–supports systems at immobilization pHs, immobilized enzyme activity, and protein load were predicted by RDID1.0 software. Afterward, immobilization was performed and predictions were experimentally confirmed. As a result, the laccase‐MANA‐Sepharose CL 4B immobilized derivative is better than laccase‐glyoxyl‐Sepharose CL 4B in predicted immobilized derivative activity (63.6% vs. 29.5%). Activity prediction was confirmed by an experimentally expressed enzymatic activity of 68%, using 2,6‐dimethoxyphenol as substrate. Experimental maximum protein load matches the estimated value (11.2 ± 1.3 vs. 12.1 protein mg/support mL). The laccase‐MANA‐Sepharose CL 4B biocatalyst has a high specificity for the acid blue 62 colorant. The results obtained in this work suggest the possibility of using this biocatalyst for wastewater treatment.

Malaria is a devastating human parasitic disease that receives enhanced attention due to the emergence of resistance to traditional drugs. Thus, the search for new molecular targets is a major goal. PfAM1 is an aminopeptidase from Plasmodium falciparum, William H. Welch 1897, belonging to the M1 family of metalloproteases, which is a promising target of inhibitors to block the intra-erythrocytic stages of the parasite. Since its identification in 1998, many efforts have been done to validate PfAM1 as an appropriate target of antimalarials. The present work is a critical review of the main structural, functional and kinetic characteristics of PfAM1, as well as a summary of the effects of key inhibitors at molecular and cellular levels. The systematization of experimental results should contribute to a better understanding of the properties of PfAM1 as a target of antimalarials and promote research projects focused on the development of PfAM1 inhibitors.
