Abstract
Phospholipase D (PLD) with the higher transphosphatidylation activity was screened from Streptomyces sp. LD0501 basing on the protoplast mutagenesis technology. Then, it was successfully bio-imprinted to form a hyperactivated structure and rigidified by the intramolecular cross-linking, which was immobilized on the nonporous nanoscale silica. Characterization techniques were employed to investigate the structure and physicochemical properties of the catalysts, including Fourier transform infrared (FTIR) spectra and scanning electron microscopy (SEM) analysis. Transphosphatidylation activity and selectivity were improved significantly when immobilized PLD was used. The maximum yield for the production of phosphatidylserine (PS) reached 97% and the side reaction, the hydrolysis, was minimized. These results were further confirmed by the nuclear magnetic resonance (NMR) and mass spectrometry (MS) analysis. The imprint-induced characteristics of PLD was successfully "remembered" even in the present of much water. In addition, this immobilized hyperactivated PLD showed the excellent operational stabilities and environmental tolerances.

Abstract
Phosphatidylserine (PS) has been widely used in the fields of food and medicine, among others, owing to its unique chemical structure and health benefits. However, the phospholipase D (PLD)-mediated enzymatic production of PS remains a challenge due to the low transphosphatidylation activity of PLD. Therefore, in the present study, we designed a maltose-binding protein (MBP) tag and a PLD co-expression method to achieve the expression of soluble PLD in Escherichia coli. A "reconstruct substrate pocket" strategy was then proposed based on the catalytic mechanism and molecular dynamics simulation, expanding the substrate pocket and manipulating the coordination of l-Ser within the active site. The best mutant (SrMBPPLDMu6) exhibited a 2.04-fold higher transphosphatidylation/hydrolysis ratio than the wild-type Furthermore, under optimal conditions, Mu6 produced 58.6 g/L PS with 77.2% conversion, within 12 h on a 3 L scale, which demonstrates the potential of the proposed method for industrial application.

Abstract
Six kinds of Mo-basing nanomaterials (MoO3 , MoO3 @Ru, Mo-PDA, MoPC , MoP, CNT@MoS2 ) were successfully synthesized, which were employed as carriers to immobilize phospholipase A1 (PLA1) for the hydrolysis of phospholipids (PLs). PLA1 was immobilized by a simple adsorption-precipitation-cross-linking to form an "enzyme net" covering on nanoparticles. The greatest advantage of these nanoparticles was their strong hydrophilic surface. It not only permitted their dispersion in the aqueous phase, but also showed the strong affinity for PLs in the organic phase, because amphiphilic PLs had the polar head group and higher hydrophilicity than other oils components. Michaelis-Menten analysis revealed that higher catalytic activity and enzyme-substrate affinity were observed in several immobilized PLA1 than its free form. MoO3 was confirmed to be the best candidate for carrier. The highest specific activity of MoO3 -immobilized PLA1 reached 43.1 U/mg, which was about 1.8 times higher than that of free PLA1 (24.4 U/mg). In addition, the stability and recycling were also enhanced. The robust immobilized PLA1 was prepared in this work, showing great potential for the enzymatic degumming.

Abstract
Owing to their numerous nutritional and bioactive functions, phospholipids (PLs), which are major components of biological membranes in all living organisms, have been widely applied as nutraceuticals, food supplements, and cosmetic ingredients. To date, PLs are extracted solely from soybean or egg yolk, despite the diverse market demands and high cost, owing to a tedious and inefficient manufacturing process. A microbial-based manufacturing process, specifically phospholipase D (PLD)-based biocatalysis and biotransformation process for PLs, has the potential to address several challenges associated with the soybean- or egg yolk-based supply chain. However, poor enzyme properties and inefficient microbial expression systems for PLD limit their wide industrial dissemination. Therefore, sourcing new enzyme variants with improved properties and developing advanced PLD expression systems are important. In the present review, we systematically summarize recent achievements and trends in the discovery, their structural properties, catalytic mechanisms, expression strategies for enhancing PLD production, and its multiple applications in the context of PLs. This review is expected to assist researchers to understand current advances in this field and provide insights for further molecular engineering efforts toward PLD-mediated bioprocessing.

Abstract
Mining of phospholipase D (PLD) with altered acyl group recognition except its head group specificity is also useful in terms of specific acyl size phospholipid production and as diagnostic reagents for quantifying specific phospholipid species. Microbial PLDs from Actinomycetes, especially Streptomyces, best fit this process requirements. In the present studies, a new PLD from marine Streptomyces klenkii (SkPLD) was purified and biochemically characterized. The optimal reaction temperature and pH of SkPLD were determined to be 60 °C and 8.0, respectively. Kinetic analysis showed that SkPLD had the relatively high catalytic efficiency toward phosphatidylcholines (PCs) with medium acyl chain length, especially 12:0/12:0-PC (67.13 S-1 mM-1), but lower catalytic efficiency toward PCs with long acyl chain (>16 fatty acids). Molecular docking results indicated that the different catalytic efficiency was related to the increased steric hindrance of long acyl-chains in the substrate-binding pockets and differences in hydrogen-bond interactions between the acyl chains and substrate-binding pockets. The enzyme displayed suitable transphosphatidylation activity and the reaction process showed 26.18% yield with L-serine and soybean PC as substrates. Present study not only enriched the PLD enzyme library but also provide guidance for the further mining of PLDs with special phospholipids recognition properties.

Abstract
Metal-driven papain-surfactant nanocomposite (PA@MSNC), a novel soft nanobiocatalyst, was successfully prepared via one-pot self-assembly technique in aqueous solution for the biosynthesis of N-(benzyloxycarbonyl)-L-alanyl-L-glutamine (Z-Ala-Gln) dipeptide in deep eutectic solvents (DESs). The metal-driven self-assembly process generated PA@MSNC as nanospheres of ˜130 nm in diameter, with high protein loading and relative enzyme activity of 420 mg/g and 80% (4270 U/g protein), respectively. PA@MSNC showed high apparent substrate affinity and catalytic efficiency. The stability of PA@MSNC at high temperature and extreme pH was significantly higher than that of free PA. Catalysis efficiency for the biosynthesis of Z-Ala-Gln by PA@MSNC in choline chloride: glycerol reaction medium was 1.69-fold higher than that of free PA, achieving a high product yield of 75.7% within 4 h. PA@MSNC also showed better techno-economic performance. We propose that enzyme-surfactant nanocomposite via metal-driven dynamically reversible coordination interactions contribute simultaneously promotes catalytic flexibility and configurational stability. The generated PA@MSNC has potential practical implications for green synthesis of dipeptide in DESs.

Abstract
Methods for enhancing enzyme activities in two-phase systems are getting more attention. Phospholipase D (PLD) was successfully encapsulated into metal-surfactant nanocapsules (MSNCs) using a one-pot self-assembly technique in an aqueous solution. The highest yield for the production of high-value phosphatidylserine (PS) from low-value phosphatidylcholine (PC) in the two-phase system was achieved by encapsulating PLD into MSNCs formed from Ca2+ which gave an enzyme activity that was 133.6% of that of free PLD. The PLD@MSNC transformed the two-phase system into an emulsion phase system and improved the organic solvent tolerance, pH and thermal stabilities as well as the storage stability and reusability of the enzyme. Under optimal conditions, PLD@MSNC generated 91.9% PS over 8 h in the two-phase system, while free PLD generated only 77.5%. PLD@MSNC transforms a two-phase system into an emulsion phase, and enhances transphosphatidylation.![]()
