Abstract
In order to preserve our livelihood for future generations, responsible use of plastics in a climate-neutral and circular economy has to be developed so that plastics can be used in an environmentally friendly way by future generations. The prerequisite is that bioplastic polymers such as polylactic acid (PLA) can be efficiently recycled from petrochemical based plastic. Here, a concept in which accelerated PLA degradation in the mixed suspension of PLA and polystyrene (PS) nanoparticles has been achieved through an engineered material binding peptide. After comparison of twenty material binding peptides, Cg-Def is selected due to its PLA binding specificity. Finally, a suitable high-throughput screening system is developed for enhancing material-specific binding toward PLA in presence of PS. Through KnowVolution campaign, a variant Cg-Def YH (L9Y/S19H) with 2.0-fold improved PLA binding specificity compared to PS is generated. Contact angle and surface plasmon resonance measurements validated higher surface coverage of Cg-Def YH on PLA surface and the fusion of Cg-Def YH with PLA degrading enzyme confirmed the accelerated PLA depolymerization (two times higher than only enzyme) in mixed PLA/PS plastics.

Abstract
Among biobased polymers, polylactic acid (PLA) is recognized as one of the most promising bioplastics to replace petrochemical-based polymers. PLA is typically blended with other polymers such as polypropylene (PP) for improved melt processability, thermal stability, and stiffness. A technical challenge in recycling of PLA/PP blends is the sorting/separation of PLA from PP. Material binding peptides (MBPs) can bind to various materials. Engineered MBPs that can bind in a material-specific manner have a high potential for material-specific detection or enhanced degradation of PLA in mixed PLA/PP plastics. To obtain a material-specific MBP for PLA binding (termed PLAbodies ), protein engineering of MBP Cg-Def for improved PLA binding specificity is reported in this work. In detail, a 96-well microtiter plate based high-throughput screening system for PLA specific binding (PLABS) was developed and validated in a protein engineering (KnowVolution) campaign. Finally, the Cg-Def variant V2 (Cg-Def S19K/K10L/N13H) with a 2.3-fold improved PLA binding specificity compared to PP was obtained. Contact angle and surface plasmon resonance measurements confirmed improved material-specific binding of V2 to PLA (1.30-fold improved PLA surface coverage). The established PLABS screening platform represents a general methodology for designing PLAbodies for applications in detection, sorting, and material-specific degradation of PLA in mixed plastics.

Abstract
PETase displays great potential in PET depolymerization. Directed evolution has been limited to engineer PETase due to the lack of high-throughput screening assay. In this study, a novel fluorescence-based high-throughput screening assay employing a newly designed substrate, bis (2-hydroxyethyl) 2-hydroxyterephthalate (termed BHET-OH), was developed for PET hydrolases. The best variant DepoPETase produced 1407-fold more products towards amorphous PET film at 50 °C and showed a 23.3 °C higher Tm value than the PETase WT. DepoPETase enabled complete depolymerization of seven untreated PET wastes and 19.1 g PET waste (0.4 % Wenzyme /WPET ) in liter-scale reactor, suggesting that it is a potential candidate for industrial PET depolymerization processes. The molecular dynamic simulations revealed that the distal substitutions stabilized the loops around the active sites and transmitted the stabilization effect to the active sites through enhancing inter-loop interactions network.

Abstract
Arginine deiminase is a well-recognized guanidino-modifying hydrolase that catalyzes the conversion of L-arginine to citrulline and ammonia. Their biopotential to regress tumors via amino acid deprivation therapy (AADT) has been well established. PEGylated formulation of recombinant Mycoplasma ADI is in the last-phase clinical trials against various arginine-auxotrophic cancers like hepatocellular carcinoma, melanoma, and mesothelioma. Recently, ADIs have attained immense importance in several other biomedical applications, namely treatment of Alzheimer's, as an antiviral drug, bioproduction of nutraceutical L-citrulline and bio-analytics involving L-arginine detection. Considering the wide applications of this biodrug, the demand for ADI is expected to escalate several-fold in the coming years. However, the sustainable production aspects of the enzyme with improved pharmacokinetics is still limited, creating bottlenecks for effective biopharmaceutical development. To circumvent the lacunae in enzyme production with appropriate paradigms of 'quality-by-design' an explicit overview of its properties with 'biobetter' formulations strategies are required. Present review provides an insight into all the potential biomedical applications of ADI along with the improvements required for its reach to clinics. Recent research advances with special emphasis on the development of ADI as a 'biobetter' enzyme have also been comprehensively elaborated.

Abstract
Lytic polysaccharide monooxygenases (LPMOs) play a crucial role in the enzymatic depolymerization of cellulose through oxidative cleavage of the glycosidic bond in the highly recalcitrant crystalline cellulose region. Improving the activity of LPMOs is of considerable importance for second-generation biorefinery. In this study, we identified a beneficial amino acid substitution (N526S) located in the cellulose binding module (CBM) of HcLPMO10 (LPMO of Hahella chejuensis) using directed evolution. The improved variant HcLPMO10 M1 (N526S) exhibits 2.1-fold higher activity for the H2O2 production, 2.7-fold higher oxidation activity, and 1.9-fold higher binding capacity toward cellulose compared with those of the wild type (WT). Furthermore, M1 shows 2.1-fold higher activity for degradation of crystalline cellulose in synergy with cellulase, compared to the WT. Structural analysis through molecular modeling and molecular dynamics (MD) simulation revealed that the substitution N526S located in the CBM likely stabilizes the cellulose binding surface and enhances the binding capacity of HcLPMO10 to cellulose, thereby enhancing enzyme activity. These findings demonstrate the important role of the CBM in the catalytic function of LPMO.

Abstract
Background:Arginine deiminase of Mycoplasma hominis, an arginine catabolizing enzyme, is currently in clinical trial for the treatment of arginine auxotrophic cancers. However, some drawbacks such as instability and antigenicity have limited its application as a protein drug. Arginine Deiminase (ADI) belongs to the guanidino-group modifying enzyme superfamily. Despite differences in the primary amino acid sequences of various members of this superfamily, the folding and secondary structures are conserved in all members. Despite structural similarities, ADIs in various species have different levels of catalytic activity and physicochemical properties due to the differences in their primary amino acid sequences. Therefore, investigating and comparing sequences between different ADI producing bacterial strains could be helpful in the rational engineering of ADI.Objective:In the current research, we used an in-silico approach to characterize and classify the available reviewed protein sequences of ADI.Results:102 ADI sequences from SwissProt database were extracted. Subsequently, based on clustering analyses, the sequence sets were divided into five distinct groups. Different physicochemical properties, solubility, and antigenicity of the enzymes were determined. Some ADI sequences were introduced as well-suited candidates for protein engineering; Lactobacillus fermentum ADI for low pI value, Mycobacterium avium ADI for high aliphatic index, Bacillus licheniformis ADI for low GRAVY index, Bradyrhizobium diazoefficiens ADI for low antigenicity and high stability index, and among Mycoplasma ADIs, Mycoplasma arthritidis ADI for high stability and aliphatic index, and Mycoplasma capricolum for low antigenicity.

Abstract
Arginine deiminase (ADI) is a therapeutic protein for cancer therapy of arginine-auxotrophic tumors. However, its application as anticancer drug is hampered by its poor stability under physiological conditions in the bloodstream. Commonly, random PEGylation is being used for increasing the stability of ADI and in turn the improved half-life. However, the traditional random PEGylation usually leads to poor PEGylation efficiency due to the limited number of Lys on the protein surface. To boost the PEGylation efficiency and enhance the stability of ADI further, surface engineering of PpADI (an ADI from Pseudomonas plecoglossicida) to increase the suitable PEGylation sites was carried out. A new in silico approach for increasing the PEGylation sites was developed. The validation of this approach was performed on previously identified PpADI variant M31 to increase potential PEGylation sites. Four Arg residues on the surface of PpADI M31 were selected through three criteria and subsequently substituted to Lys, aiming for providing primary amines for PEGylation. Two out of the four substitutions (R299K and R382K) enhanced the stability of PEGylated PpADI in human serum. The average numbers of PEGylation sites were increased from ~12 (tetrameric PpADI M31, starting point) to ~20 (tetrameric PpADI M36, final variant). Importantly, the PEGylated PpADI M36 after PEGylation exhibited significantly improved Tm values (M31: 40°C; M36: 40°C; polyethylene glycol [PEG]-M31: 54°C; PEG-M36: 64°C) and half-life in human serum (M31: 1.9 days; M36: 2.0 days; PEG-M31: 3.2 days; PEG-M36: 4.8 days). These proved that surface engineering is an effective approach to increase the PEGylation efficiency which therefore enhances the stability of therapeutic enzymes. Furthermore, the PEGylated PpADI M36 represents a highly attractive candidate for the treatment of arginine-auxotrophic tumors.

Abstract
Downstream processing to obtain enantiopure compounds from a racemic mixture relies mainly on crystallization. Natural transporters can specifically translocate enantiomers through membranes. Here a β-barrel transmembrane protein FhuA is re-engineered into a chiral channel protein (FhuAF4) to resolve racemic mixtures of d-/l-arginine. The engineered FhuAF4 variant exhibits an enantioselectivity (E-value) of 1.92 and an enantiomeric excess percentage (ee%) of 23.91 at 52.39% conversion. OmniChange mutant libraries at the computationally identified "filter-regions" likely help to identify FhuA variants for enantiomeric separation of other compounds.

Abstract
For more than thirty years, biotechnology has borne witness to the power of directed evolution in designing molecules of industrial relevance. While scientists all over the world discuss the future of molecular evolution, dozens of laboratory-designed products are being released with improved characteristics in terms of turnover rates, substrate scope, catalytic promiscuity or stability. In this review we aim to present the most recent advances in this fascinating research field that are allowing us to surpass the limits of nature and apply newly gained attributes to a range of applications, from gene therapy to novel green processes. The use of directed evolution in non-natural environments, the generation of catalytic promiscuity for non-natural reactions, the insertion of unnatural amino acids into proteins or the creation of unnatural DNA, is described comprehensively, together with the potential applications in bioremediation, biomedicine and in the generation of new bionanomaterials. These successful case studies show us that the limits of directed evolution will be defined by our own imagination, and in some cases, stretching beyond that.

Abstract
A ligand-mediated eGFP-expression system (LiMEx) was developed as a novel flow cytometry based screening platform that relies on a competitive conversion/binding of arginine between arginine deiminase and arginine repressor. Unlike product-driven detection systems, the competitive screening platform allows to evolve enzymes toward efficient operation at low substrate concentrations under physiological conditions. The principle of LiMEx was validated by evolving arginine deiminase (ADI, an anticancer therapeutic) for stronger inhibition of tumor growth. After screening of ∼8.2 × 10(6) clones in three iterative rounds of epPCR libraries, PpADI (ADI from Pseudomonas plecoglossicida) variant M31 with reduced S0.5 value (0.17 mM compared to 1.23 mM (WT)) and, importantly, increased activity at physiological arginine concentration (M31:6.14 s(-1); WT: not detectable) was identified. Moreover, M31 showed a significant inhibitory effect against SK-MEL-28 and G361 melanoma cell lines. (IC50 = 0.02 μg/mL for SK-MEL-28 and G361).

Abstract
Arginine deiminase (ADI) is a therapeutic protein for cancer therapy of arginine-auxotrophic tumors. However, ADI's application as anticancer drug is hampered by its low activity for arginine under physiological conditions mainly due to its high "K M" (S₀.₅) values which are often 1 magnitude higher than the arginine concentration in blood (0.10-0.12 mM arginine in human plasma). Previous evolution campaigns were directed by us with the aim of boosting activity of PpADI (ADI from Pseudomonas plecoglossicida, k cat = 0.18 s(-1); S₀.₅ = 1.30 mM), and yielded variant M6 with slightly reduced S₀.₅ values and enhanced k cat (S₀.₅ = 0.81 mM; k cat = 11.64 s(-1)). In order to further reduce the S₀.₅ value and to increase the activity of PpADI at physiological arginine concentration, a more sensitive screening system based on ammonia detection in 96-well microtiter plate to reliably detect ≥0.005 mM ammonia was developed. After screening ~5,500 clones with the ammonia detection system (ADS) in two rounds of random mutagenesis and site-directed mutagenesis, variant M19 with increased k cat value (21.1 s(-1); 105.5-fold higher compared to WT) and reduced S₀.₅ value (0.35 mM compared to 0.81 mM (M6) and 1.30 mM (WT)) was identified. Improved performance of M19 was validated by determining IC₅₀ values for two melanoma cell lines. The IC₅₀ value for SK-MEL-28 dropped from 8.67 (WT) to 0.10 (M6) to 0.04 μg/mL (M19); the IC₅₀ values for G361 dropped from 4.85 (WT) to 0.12 (M6) to 0.05 μg/mL (M19).

Abstract
Directed evolution offers opportunities to improve promiscuous activities of hydrolases in rounds of diversity generation and high-throughput screening. In this article, we developed and validated a screening platform to improve the perhydrolytic activity of proteases and likely other hydrolases (e.g., lipases or esterases). Key was the development of a highly sensitive fluorescent assay (sensitivity in the µM range) based on 3-carboxy-7-hydroxycoumarin (HCC) formation. HCC is released through an hypobromite-mediated oxidation of 7-(4′-aminophenoxy)-3-carboxycoumarin (APCC), which enables for the first time a continuous measurement of peroxycarboxylic acid formation with a standard deviation of 11% in microtiter plates with a wide pH range window (5–9). As example, subtilisin Carlsberg was subjected to site saturation mutagenesis at position G165, yielding a variant T58A/G165L/L216W with 5.4-fold increased kcat for perhydrolytic activity compared with wild type.
