Methanol and ethanol are representative C1 and C2 compounds, which can be used as bio-renewable platform feedstocks for the biotechnological production of value-added natural chemicals. Methanol-derived formaldehyde and ethanol-derived acetaldehyde can be converted to 3-hydroxypropanal (3-HPA) via aldol condensation. 3-HPA is used in food preservation and as a precursor for 3-hydroxypropionic acid and 1,3-propanediol that are starting materials for manufacturing biocompatible plastic and polytrimethylene terephthalate. In this study, 3-HPA was biosynthesized from formaldehyde and acetaldehyde using deoxyribose-5-phosphate aldolase from Thermotoga maritima (DERATma) and cloned and expressed in Escherichia coli for 3-HPA production. Under optimum conditions, DERATma produced 7 mM 3-HPA from 25 mM substrate (formaldehyde and acetaldehyde) for 60 min with 520 mg\/L\/h productivity. To demonstrate the one-pot 3-HPA production from methanol and ethanol, we used methanol dehydrogenase from Lysinibacillus xylanilyticus (MDHLx) and DERATma. One-pot 3-HPA production via aldol condensation of formaldehyde and acetaldehyde from methanol and ethanol, respectively, was investigated under optimized reaction conditions. This is the first report on 3-HPA production from inexpensive alcohol substrates (methanol and ethanol) by cascade reaction using DERATma and MDHLx.<\/jats:p>","DOI":"10.3390\/ijms23073990","type":"journal-article","created":{"date-parts":[[2022,4,3]],"date-time":"2022-04-03T06:04:01Z","timestamp":1648965841000},"page":"3990","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["In Vitro One-Pot 3-Hydroxypropanal Production from Cheap C1 and C2 Compounds"],"prefix":"10.3390","volume":"23","author":[{"given":"Su-Bin","family":"Ju","sequence":"first","affiliation":[{"name":"School of Biological Sciences and Biotechnology, Graduate School, Chonnam National University, Yong-bong-ro 77, Gwangju 61186, Korea"},{"name":"School of Biological Sciences and Technology, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4792-0093","authenticated-orcid":false,"given":"Min-Ju","family":"Seo","sequence":"additional","affiliation":[{"name":"School of Biological Sciences and Technology, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Soo-Jin","family":"Yeom","sequence":"additional","affiliation":[{"name":"School of Biological Sciences and Biotechnology, Graduate School, Chonnam National University, Yong-bong-ro 77, Gwangju 61186, Korea"},{"name":"School of Biological Sciences and Technology, Chonnam National University, Gwangju 61186, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"260","DOI":"10.1186\/s13068-018-1265-y","article-title":"Current advance in bioconversion of methanol to chemicals","volume":"11","author":"Zhang","year":"2018","journal-title":"Biotechnol.
