Abstract
Penicillin G acylase (PGA) is a strategic enzyme in the production processes of beta-lactam antibiotics. High demand for β-lactam semisynthetic antibiotics explain the genetic and biochemical engineering strategies devoted towards novel ways for PGA production and application. This work presents a fermentation process for the heterologous production of PGA from Alcaligenes faecalis in Bacillus megaterium with optimization. The thermal stability from A. faecalis PGA is considerably higher than other described PGA and the recombinant enzyme is secreted to the culture medium by B. megaterium, which facilitates the separation and purification steps. Media optimization using fractional factorial design experiments was used to identify factors related to PGA activity detection in supernatant and cell lysates. The optimized medium resulted in almost 6-fold increased activity in the supernatant samples when compared with the basal medium. Maximum enzyme activity in optimized medium composition achieves values between 135 and 140 IU/ml. The results suggest a promising model for recombinant production of PGA in B. megaterium with possible extracellular expression of the active enzyme.

Abstract
Penicillin G acylase (PGA) is a key biocatalyst for the enzymatic production of β-lactam antibiotics, which can not only catalyze the synthesis of β-lactam antibiotics but also catalyze the hydrolysis of the products to prepare semi-synthetic antibiotic intermediates. However, the high hydrolysis and low synthesis activities of natural PGAs severely hinder their industrial application. In this study, a combinatorial directed evolution strategy was employed to obtain new PGAs with outstanding performances. The best mutant βF24G/βW154G was obtained from the PGA of Achromobacter sp., which exhibited approximately a 129.62-fold and a 52.55-fold increase in specific activity and synthesis/hydrolysis ratio, respectively, compared to the wild-type AsPGA. Thereafter, this mutant was used to synthesize amoxicillin, cefadroxil, and ampicillin; all conversions > 99% were accomplished in 90-135 min with almost no secondary hydrolysis byproducts produced in the reaction. Molecular dynamics simulation and substrate pocket calculation revealed that substitution of the smallest glycine residue at βF24 and βW154 expanded the binding pocket, thereby facilitating the entry and release of substrates and products. Therefore, this novel mutant is a promising catalyst for the large-scale production of β-lactam antibiotics.

Abstract
Penicillin G acylase plays an important role in the biocatalytic process of semi-synthetic penicillin. In order to overcome the disadvantages of free enzymes and improve the catalytic performance of enzymes, it is a new method to immobilize enzymes on carrier materials. And magnetic materials have the characteristics of easy separation. In the present study, the Magnetic Ni0.3Mg0.4Zn0.3Fe2O4 nanoparticles were successfully prepared by a rapid-combustion method and calcined at 400°C for 2 h. The surface of the nanoparticles was modified with sodium silicate hydrate, and the PGA was covalently bound to the carrier particles through the cross-linking of glutaraldehyde. The results showed that the activity of immobilized PGA reached 7121.00 U/g. The optimum pH for immobilized PGA was 8 and the optimum temperature was 45°C, the immobilized PGA exhibited higher stability against changes in pH and temperature. The Michaelis–Menten constant (Km) values of the free and immobilized PGA were 0.00387 and 0.0101 mol/L and the maximum rate (Vmax) values were 0.387 and 0.129 μmol/min. Besides, the immobilized PGA revealed excellent cycling performance. The immobilization strategy presented PGA had the advantages of reuse, good stability, cost saving and had considerable practical significance for the commercial application of PGA.

Structural and enzymatic analysis of a dimeric cholylglycine hydrolase like acylase active on N-acyl homoserine lactones. Biochimie 2020; 177:108-116.

Abstract
The prevalence of substrate cross-reactivity between AHL acylases and β-lactam acylases provides a glimpse of probable links between quorum sensing and antibiotic resistance in bacteria. Both these enzyme classes belong to the N-terminal nucleophile (Ntn)-hydrolase superfamily. Penicillin V acylases alongside bile salt hydrolases constitute the cholylglycine hydrolase (CGH) group of the Ntn-hydrolase superfamily. Here we report the ability of two acylases, Slac1 and Slac2, from the marine bacterium Shewanella loihica-PV4 to hydrolyze AHLs. Three-dimensional structure of Slac1reveals the conservation of the Ntn hydrolase fold and CGH active site, making it a unique CGH exclusively active on AHLs. Slac1homologs phylogenetically cluster separate from reported CGHs and AHL acylases, thereby representing a functionally distinct sub-class of CGH that might have evolved as an adaptation to the marine environment. We hypothesize that Slac1 could provide the structural framework for understanding this subclass, and further our understanding of the evolutionary link between AHL acylases and β-lactam acylases.

Abstract
Penicillin acylases (penicillin amidohydrolase, EC 3.5.1.11) are a group of enzymes with many applications within the pharmaceutical industry, and one of them is the production of semi-synthetic beta-lactam antibiotics. This enzyme is mainly produced by bacteria but also by some fungi. In the present study, the filamentous fungus Mucor griseocyanus was used to produce penicillin acylase enzyme (PGA). Its ability to express PGA enzyme in submerged fermentation process was assessed, finding that this fungal strain produces the biocatalyst of interest in an extracellular way at a level of 570 IU/L at 72 h of fermentation; in this case, a saline media using lactose as carbon source and penicillin G as inducer was employed. In addition, a DNA fragment (859 bp) of the pga from a pure Mucor griseocyanus strain was amplified, sequenced, and analyzed in silico. The partial sequence of pga identified in the fungi showed high identity percentage with penicillin G acylase sequences deposited in NCBI through BLAST, especially with the β subunit of PGA from the Alcaligenes faecalis bacterium¸ which is a region involved in the catalytic function of this protein. Besides, the identification of domains in the penicillin G acylase sequence of Mucor griseocyanus showed three conserved regions of this protein. The bioinformatic results support the identity of the gen as penicillin G acylase. This is the first report that involves sequencing and in silico analysis of Mucor griseocyanus strain gene encoding PGA.

Abstract
Penicillin G acylase (PGA) catalyzes the hydrolysis of penicillin G to 6-aminopenicillanic acid and phenylacetic acid, which provides the precursor for most semisynthetic penicillins. Most applications rely on PGAs from Gram-negative bacteria. Here we describe the first three crystal structures for PGAs from Gram-positive Bacilli and their utilization in protein engineering experiments for the manipulation of their thermostability. PGAs from Bacillus megaterium (BmPGA, Tm = 56.0 °C), Bacillus thermotolerans (BtPGA, Tm = 64.5 °C), and Bacillus sp. FJAT-27231 (FJAT-PGA, Tm = 74.3 °C) were recombinantly produced with B. megaterium, secreted, purified to apparent heterogeneity, and crystallized. Structures with resolutions of 2.20 Å (BmPGA), 2.27 Å (BtPGA), and 1.36 Å (FJAT-PGA) were obtained. They revealed high overall similarity, reflecting the high identity of up to approx. 75%. Notably, the active center displays a deletion of more than ten residues with respect to PGAs from Gram-negatives. This enlarges the substrate binding site and may indicate a different substrate spectrum. Based on the structures, ten single-chain FJAT-PGAs carrying artificial linkers were produced. However, in all cases, complete linker cleavage was observed. While thermostability remained in the wild-type range, the enzymatic activity dropped between 30 and 60%. Furthermore, four hybrid PGAs carrying subunits from two different enzymes were successfully produced. Their thermostabilities mostly lay between the values of the two mother enzymes. For one PGA increased, enzyme activity was observed. Overall, the three novel PGA structures combined with initial protein engineering experiments provide the basis for establishment of new PGA-based biotechnological processes.
