Abstract
After major mass extinction events, ancient plants and terrestrial vertebrates were faced with various challenges, especially ultraviolet (UV) light. These stresses probably resulted in changes in the biosynthetic pathways, which employed the MIO (3,5-dihydro-5-methylidene-4H-imidazole-4-one)-dependent enzymes (ammonia-lyase and aminomutase), leading to enhanced accumulation of metabolites for defense against UV radiation, pathogens, and microorganisms. Up to now, the origin and evolution of genes from this superfamily have not been extensively studied. In this report, we perform an analysis of the phylogenetic relations between the members of the aromatic amino acid MIO-dependent enzymes (AAM), which demonstrate that they most probably have a common evolutionary origin from ancient bacteria. In early soil environments, numerous bacterial species with tyrosine ammonia-lyase genes (TAL; EC 4.3.1.23) developed tyrosine aminomutase (TAM; EC 5.4.3.6) activity as a side reaction for competing with their neighbors in the community. These genes also evolved into other TAL-like enzymes, such as histidine ammonia-lyase (HAL, EC 4.3.1.3) and phenylalanine ammonia-lyase (PAL; EC 4.3.1.24), in different bacterial species for metabolite production and accumulation for adaptation to adverse terrestrial environmental conditions. On the other hand, the existence of phenylalanine aminomutase (PAM; EC 5.4.3.10) and phenylalanine/tyrosine ammonia-lyase (PTAL; EC 4.3.1.25) strongly indicates the horizontal gene transfer (HGT) between bacteria, fungi, and plants in symbiotic association after acquiring the PAL gene from their ancestor.

Abstract
Phenylalanine aminomutase from Taxus chinensis (TchPAM) is employed in the biosynthesis of the widely used antitumor drug paclitaxel. TchPAM has received substantial attention due to its strict enantioselectivity towards (R)-β-phenylalanine, in contrast to the bacterial enzymes classified as EC 5.4.3.11 which are (S)-selective for this substrate. However, the understanding of the isomerization mechanism of the reorientation and rearrangement reactions in TchPAM might support and promote further research on expanding the scope of the substrate and thus the establishment of large-scale production of potential synthesis for drug development. Upon conservation analysis, computational simulation, and mutagenesis experiments, we report a mutant from TchPAM, which can catalyze the amination reaction of trans-p-hydroxycinnamic acid to (R)- and (S)-β-tyrosine. We propose a mechanism for the function of the highly conserved residues L179, N458, and Q459 in the active site of TchPAM. This work highlights the importance of the hydrophobic residues in the active site, including the residues L104, L108, and I431, for maintaining the strict enantioselectivity of TchPAM, and the importance of these residues for substrate specificity and activation by altering the substrate binding position or varying the location of neighboring residues. Furthermore, an explanation of (R)-selectivity in TchPAM is proposed based on the mutagenesis study of these hydrophobic residues. In summary, these studies support the future exploitation of the rational engineering of corresponding enzymes with MIO moiety (3,5-dihydro-5-methylidene-4H-imidazole-4-one) such as ammonia lyases and aminomutases of aromatic amino acids.

Abstract
Lignin is an underutilized sustainable source of aromatic compounds. To valorize the low-value lignin monomers, we proposed an efficient strategy, involving enzymatic conversion from trans-p-hydroxycinnamic acids to generate valued-added canonical and non-canonical aromatic amino acids. Among them, β-amino acids are recognized as building blocks for bioactive natural products and pharmaceutical ingredients due to their attractive antitumor properties. Using computational enzyme design, the (R)-β-selective phenylalanine aminomutase from Taxus chinensis (TchPAM) was successfully mutated to accept β-tyrosine as the substrate, as well as to generate the (R)-β-tyrosine with excellent enantiopurity (ee > 99%) as the unique product from trans-p-hydroxycinnamic acid. Moreover, the kinetic parameters were determined for the reaction of four Y424 enzyme variants with the synthesis of different phenylalanine and tyrosine enantiomers. In the ammonia elimination reaction of (R)-β-tyrosine, the variants Y424N and Y424C displayed a two-fold increased catalytic efficiency of the wild type. In this work, a binding pocket in the active site, including Y424, K427, I431, and E455, was examined for its influence on the β-enantioselectivity of this enzyme family. Combining the upstream lignin depolymerization and downstream production, a sustainable value chain based on lignin is enabled. In summary, we report a β-tyrosine synthesis process from a monolignol component, offering a new way for lignin valorization by biocatalyst modification.

Investigation into isomerization reaction of phenylalanine aminomutase from Pantoea agglomerans. Enzyme Microb Technol 2019; 132:109428.

Abstract
Phenylalanine aminomutase (PaPAM) from Pantoea agglomerans is a member of the MIO (4-methylene-imidazol-5-one) family of enzymes, which isomerizes α-phenylalanine to β-phenylalanine, and could be used to synthesize unnatural β-arylalanine. However, the mechanism of isomerization reaction is not clear. To investigate the mechanism, the gene (pam), which encodes PaPAM, was first expressed in E.coli, and recombinant PaPAM was prepared using affinity chromatography. Then, 15N-(2S)-α-phenylalanine, (2S)-(3-2H2)-α-phenylalanine and (2S,3S)-[2,3-2H2]-α-phenylalanine were used as substrates to analyze the mechanism of isomerization reaction. The results of MS and NMR showed that the isomerization reaction was performed through the intramolecular exchange of NH2 with pro-3R hydrogen of α-phenylalanine. The PaPAM shuttles the α-NH2 of α-phenylalanine to β site to replace the pro-3R hydrogen. Simultaneously, the pro-3R hydrogen is shifted to α site to produce β-phenylalanine. Furthermore, a key residue, Phe at position 455 in the active site, was determined to control the exchange way using molecular docking and sequence alignment of MIO family enzymes. The results indicated that the key 455 Phe residue is involved in changing the binding orientation of the carboxyl group of the intermediate trans-cinnamic acid to control the NH2-H pair exchange.

Abstract
α,β-Dehydroamino acids (dhAAs) are noncanonical amino acids that are found in a wide array of natural products and can be easily installed into peptides and proteins. dhAAs exhibit remarkable synthetic flexibility, readily undergoing a number of reactions, such as polar and single-electron additions, transition metal catalyzed cross-couplings, and cycloadditions. Because of the relatively mild conditions required for many of these reactions, dhAAs are increasingly being used as orthogonal chemical handles for late-stage modification of biomolecules. Still, only a fraction of the chemical reactivity of dhAAs has been exploited in such biorthogonal applications. Herein, we provide an overview of the broad spectrum of chemical reactivity of dhAAs, with special emphasis on recent efforts to adapt such transformations for biomolecules such as natural products, peptides, and proteins. We also discuss examples of enzymes from natural product biosynthetic pathways that have been found to catalyze many similar reactions; these enzymes provide mild, regio- and stereoselective, biocatalytic alternatives for future development. We anticipate that the continued investigation of the innate reactivity of dhAAs will furnish a diverse portfolio dhAA-based chemistries for use in chemical biology and drug discovery.

Abstract
Seven 1,10-secoguaianolides 1⁻7, including a new one (compound 1), were isolated from Artemisia austro-yunnanensis and identified by HRESIMS and other spectroscopic methods. Their anti-inflammatory effects were evaluated by the model of LPS-induced RAW264.7 cells in vitro. Bioassay results showed that six of them (1⁻4, 6 and 7), with the exception of 5, produce some cytotoxicity on RAW264.7 cells at its high dosage, can significantly decrease the release of NO, TNF-α, IL-1β, IL-6 and PGE2 in a dose dependent manner, and down-regulate the expression of proteins iNOS and COX-2. The mechanism study indicated they regulated the NF-κB dependent transcriptional activity through decreasing the phosphorylation of NF-κB. Further, the relationship between their structures and cytokines to anti-inflammatory were studied by PCA and discussed.

Abstract
The phenylalanine ammonia-lyase (AvPAL) from Anabaena variabilis catalyzes the amination of substituent trans-cinnamic acid (t-CA) to produce racemic D,L-enantiomer arylalanine mixture owing to its low stereoselectivity. To produce high optically pure D-arylalanine, a modified AvPAL with high D-selectivity is expected. Based on the analyses of catalytic mechanism and structure, the Asn347 residue in the active site was proposed to control stereoselectivity. Therefore, Asn347 was mutated to construct mutant AvPAL-N347A, the stereoselectivity of AvPAL-N347A for D-enantiomer arylalanine was 2.3-fold higher than that of wild-type AvPAL (WtPAL). Furthermore, the residual L-enantiomer product in reaction solution could be converted into the D-enantiomer product through stereoselective oxidation by PmLAAD and nonselective reduction by reducing agent NH3BH3. At optimal conditions, the conversion rate of t-CA and optical purity (enantiomeric excess (eeD)) of D-phenylalanine reached 82% and exceeded 99%, respectively. The two enzymes displayed activity toward a broad range of substrate and could be used to efficiently synthesize D-arylalanine with different groups on the phenyl ring. Among these D-arylalanines, the yield of m-nitro-D-phenylalanine was highest and reached 96%, and the eeD exceeded 99%. This one-pot synthesis using AvPAL and PmLAAD has prospects for industrial application.

Abstract
Phenylalanine aminomutase (TcPAM) from Taxus chinensis catalyzes the regioselective hydroamination of trans-cinnamic acid (t-CA) to yield β-phe. However, the final product mixture consists of both α- and β-phe owing to low regioselectivity, which is still a challenge to synthesize highly pure β-phe. Therefore, a modified TcPAM with high β-selectivity is expected. Based on the catalytic mechanism and structure, two amino acid residues (Asn458 and Leu108) in active sites were identified as the key residues for controlling the regioselective hydroamination of t-CA and as promising candidates for mutagenesis to enhance β-selectivity and decrease α-selectivity. The Asn458 and Leu108 residues were mutated to yield variant TcPAM-Asn458Phe/Leu108Glu, and the β-selectivity was approximately 5.2-fold higher than that of wild-type TcPAM, while α-selectivity decreased to 68%, and the percentage of β-phe in the product mixture increased from 42% to 83%. In addition, the mutant was applied to synthesize β-arylalanines using substituent t-CA as a substrate. The regioselectivity was also affected by the substituent groups at the phenyl ring of t-CA with respect to their electronic properties and position, and the 4-methoxy and methyl substituent t-CA were transferred into β-arylalanines. The conversion rate also exceeded 90%. In summary, the engineered TcPAM proved to be useful for one-step asymmetric amination of t-CA and its derivatives to synthesize highly pure β-arylalanines.

Abstract
The suite of biological catalysts found in Nature has the potential to contribute immensely to scientific advancements, ranging from industrial biotechnology to innovations in bioenergy and medical intervention. The endeavour to obtain a catalyst of choice is, however, wrought with challenges. Herein we report the design of a structure-based annotation system for the identification of functionally similar enzymes from diverse sequence backgrounds. Focusing on an enzymatic activity with demonstrated synthetic and therapeutic relevance, five new phenylalanine ammonia lyase (PAL) enzymes were discovered and characterised with respect to their potential applications. The variation and novelty of various desirable traits seen in these previously uncharacterised enzymes demonstrates the importance of effective sequence annotation in unlocking the potential diversity that Nature provides in the search for tailored biological tools. This new method has commercial relevance as a strategy for assaying the ‘evolvability’ of certain enzyme features, thus streamlining and informing protein engineering efforts.

Abstract
Aromatic amino acid ammonia‐lyases and aromatic amino acid 2,3‐aminomutases contain the post‐translationally formed prosthetic 3,5‐dihydro‐4‐methylidene‐5H‐imidazol‐5‐one (MIO) group. MIO enzymes catalyze the stereoselective synthesis of α‐ or β‐amino acid enantiomers, making these chemical processes environmentally friendly and affordable. Characterization of novel inhibitors enables structural understanding of enzyme mechanism and recognizes promising herbicide candidates as well. The present study found that both enantiomers of the aminophosphonic acid analogue of the natural substrate phenylalanine and a novel derivative bearing a methylidene at the β‐position inhibited phenylalanine ammonia‐lyases (PAL), representing MIO enzymes. X‐ray methods unambiguously determined the absolute configuration of all tested enantiomers during their synthesis. Enzyme kinetic measurements revealed the enantiomer of the methylidene‐substituted substrate analogue as being a mirror image relation to the natural l‐phenylalanine as the strongest inhibitor. Isothermal titration calorimetry (ITC) confirmed the binding constants and provided a detailed analysis of the thermodynamic driving forces of ligand binding. Molecular docking suggested that binding of the (R)‐ and (S)‐enantiomers is possible by a mirror image packing. ![]()

Abstract
The substrate scope of phenylalanine ammonia-lyase from Petroselinum crispum (PcPAL) towards the l-enantiomers of racemic styrylalanines rac-1a–d were extended by reshaping the aromatic binding pocket of the active site of PcPAL by point mutations of F137.

Abstract
Deciphering the structural features that functionally separate ammonia lyases from aminomutases is of interest because it may allow for the engineering of more efficient aminomutases for the synthesis of unnatural amino acids (e.g., β-amino acids). However, this has proved to be a major challenge that involves understanding the factors that influence their activity and regioselectivity differences. Herein, we report evidence of a structural determinant that dictates the activity differences between a phenylalanine ammonia lyase (PAL) and aminomutase (PAM). An inner loop region that closes the active sites of both PAM and PAL was mutated within PAM (PAM residues 77-97) in a stepwise approach to study the effects when the equivalent residue(s) found in the PAL loop were introduced into the PAM loop. Almost all of the single loop mutations triggered a lyase phenotype in PAM. Experimental and computational evidence suggest that the induced lyase features result from inner loop mobility enhancements, which are possibly caused by a 310-helix cluster, flanking α-helices, and hydrophobic interactions. These findings pinpoint the inner loop as a structural determinant of the lyase and mutase activities of PAM.
