Abstract
Pathway engineering is a useful technology for producing desired compounds on a large scale by modifying the biosynthetic pathways of host organisms using genetic engineering. We focused on acetoacetate esters as novel low-cost substrates and established an efficient terpenoid production system using pathway-engineered recombinant Escherichia coli. Functional analysis using recombinant E. coli proteins of 18 carboxylesterases identified from the microbial esterases and lipases database showed that the p-nitrobenzyl esterase (PnbA) from Bacillus subtilis specifically hydrolyzed two acetoacetate esters: methyl acetoacetate (MAA) and ethyl acetoacetate (EAA). We generated a plasmid (pAC-Mev/Scidi/Aacl/PnbA) co-expressing PnbA and six enzymes of the mevalonate pathway gene cluster from Streptomyces, isopentenyl diphosphate isomerase type I from Saccharomyces cerevisiae, and acetoacetyl-coenzyme A ligase from Rattus norvegicus. The plasmid pAC-Mev/Scidi/Aacl/PnbA was introduced into E. coli along with plasmid expressing carotenoid (lycopene) or sesquiterpene (β-bisabolene) biosynthesis genes, and the terpenoid production was evaluated following the addition of acetoacetate esters as substrates. These recombinant E. coli strains used MAA and EAA as substrates for the biosynthesis of terpenoids and produced almost equivalent concentrations of target compounds compared with the previous production system that used mevalonolactone and lithium acetoacetate. The findings of this study will enable the production of useful terpenoids from low-cost substrates, which may facilitate their commercial production on an industrial scale in the future. KEY POINTS: • PnbA from Bacillus subtilis exhibits acetoacetate hydrolysis activity. • A plasmid enabling terpenoid synthesis from acetoacetate esters was constructed. • Acetoacetate esters as substrates enable a low-cost production of terpenoids.

Abstract
The two enantiomers of ethyl 3-hydroxybutyrate are important intermediates for the synthesis of a great variety of valuable chiral drugs. The preparation of chiral drug intermediates through kinetic resolution reactions catalyzed by esterases/lipases has been demonstrated to be an efficient and environmentally friendly method. We previously functionally characterized microbial esterase PHE21 and used PHE21 as a biocatalyst to generate optically pure ethyl (S)-3-hydroxybutyrate. Herein, we also functionally characterized one novel salt-tolerant microbial esterase WDEst17 from the genome of Dactylosporangium aurantiacum subsp. Hamdenensis NRRL 18085. Esterase WDEst17 was further developed as an efficient biocatalyst to generate (R)-3-hydroxybutyrate, an important chiral drug intermediate, with the enantiomeric excess being 99% and the conversion rate being 65.05%, respectively, after process optimization. Notably, the enantio-selectivity of esterase WDEst17 was opposite than that of esterase PHE21. The identification of esterases WDEst17 and PHE21 through genome mining of microorganisms provides useful biocatalysts for the preparation of valuable chiral drug intermediates.

Production of chiral alcohols from prochiral ketones by microalgal photo-biocatalytic asymmetric reduction reaction. J Ind Microbiol Biotechnol 2012; 39:835-41. [PMID: 22322691 DOI: 10.1007/s10295-012-1088-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2011] [Accepted: 01/12/2012] [Indexed: 10/14/2022]
Abstract
Microalgal photo-biocatalysis is a green technique for asymmetric synthesis. Asymmetric reduction of nonnatural prochiral ketones to produce chiral alcohols by microalgal photo-biocatalysis was studied in this work. Acetophenone (ACP) and ethyl acetoacetate (EAA) were chosen as model substrates for aromatic ketones and β-ketoesters, respectively. Two prokaryotic cyanophyta and two eukaryotic chlorophyta were selected as photo-biocatalysts. The results proved that nonnatural prochiral ketones can be reduced by microalgal photo-biocatalysis with high enantioselectivity. Illumination is indispensable to the photo-biocatalysis. For aromatic ketone, cyanophyta are eligible biocatalysts. For ACP asymmetric reduction reaction, about 45% yield and 97% e.e. can be achieved by the photo-biocatalysis reaction with Spirulina platensis as biocatalyst. On the contrary, chlorophyta are efficient biocatalysts for β-ketoester asymmetric reduction reaction among the four tested algae. For EAA asymmetric reduction reaction, about 70% yield and 90% e.e. can be achieved with Scenedesmus obliquus as biocatalyst. The microalgae used in this study outperformed other characterized biocatalysts such as microbial and plant cells.
