[PMID: 33636334 DOI: 10.1016/j.freeradbiomed.2021.02.023] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 02/10/2021] [Accepted: 02/13/2021] [Indexed: 10/22/2022]
Abstract
Aminoacetone (1-aminopropan-2-one), a putative minor biological source of methylglyoxal, reacts like other α-aminoketones such as 6-aminolevulinic acid (first heme precursor) and 1,4-diaminobutanone (a microbicide) yielding electrophilic α-oxoaldehydes, ammonium ion and reactive oxygen species by metal- and hemeprotein-catalyzed aerobic oxidation. A plethora of recent reports implicates triose phosphate-generated methylglyoxal in protein crosslinking and DNA addition, leading to age-related disorders, including diabetes. Importantly, methylglyoxal-treated hemoglobin adds four water-exposed arginine residues, which may compromise its physiological role and potentially serve as biomarkers for diabetes. This paper reports on the co-oxidation of aminoacetone and oxyhemoglobin in normally aerated phosphate buffer, leading to structural changes in hemoglobin, which can be attributed to the addition of aminoacetone-produced methylglyoxal to the protein. Hydroxyl radical-promoted chemical damage to hemoglobin may also occur in parallel, which is suggested by EPR-spin trapping studies with 5,5-dimethyl-1-pyrroline-N-oxide and ethanol. Concomitantly, oxyhemoglobin is oxidized to methemoglobin, as indicated by characteristic CD spectral changes in the Soret and visible regions. Overall, these findings may contribute to elucidate the molecular mechanisms underlying human diseases associated with hemoglobin dysfunctions and with aminoacetone in metabolic alterations related to excess glycine and threonine.

Abstract
5-Aminolevulinic acid (ALA) is a value-added compound with potential applications in the fields of agriculture and medicine. Although massive efforts have recently been devoted to building microbial producers of ALA through metabolic engineering, few studies focused on the cellular response and tolerance to ALA. In this study, we demonstrated that ALA caused severe cell damage and morphology change of Escherichia coli via generating reactive oxygen species (ROS), which were further determined to be mainly hydrogen peroxide and superoxide anion radical. ALA treatment activated the native antioxidant defense system by upregulating catalase (CAT) and superoxide dismutase (SOD) expression to combat ROS. Further overexpressing CAT (encoded by katG and katE) and SOD (encoded by sodA, sodB, and sodC) not only improved ALA tolerance but also its production level. Notably, coexpression of katE and sodB in an ALA synthase expressing strain enhanced the biomass and final ALA titer by 81% and 117% (11.5 g/L) in a 5 L bioreactor, respectively. This study demonstrates the importance of tolerance engineering in strain development. Reinforcing the antioxidant defense system holds promise to improve the bioproduction of chemicals that cause oxidative stress.

Abstract
The azinomycins are a family of aziridine-containing antitumor antibiotics and represent a treasure trove of biosynthetic reactions. The formation of the azabicyclo[3.1.0]hexane ring and functionalization of this ring system remain the least understood aspects of the pathway. This study reports the incorporation of 18O-labeled molecular oxygen in azinomycin biosynthesis including both oxygens of the diol that ultimately adorn the aziridino[1,2- a]pyrrolidine moiety. Likewise, two other sites of heavy atom incorporation are observed.

Abstract
We have established the biosynthetic pathway and the associated genes for the biosynthesis of the 5-(aminomethyl)-3-furanmethanol (F1) moiety of methanofuran in the methanogenic archaeon Methanocaldococcus jannaschii. The recombinant enzyme, derived from the MJ1099 gene, was shown to readily condense glyceraldehyde 3-phosphate (Ga-3P) and dihydroxyacetone-P (DHAP) to form 4-(hydroxymethyl)-2-furancarboxaldehyde phosphate (4-HFC-P). The recombinant purified pyridoxal 5'-phosphate-dependent aminotransferase, derived from the MJ0684 gene, was found to be specific for catalyzing the transamination reaction between 4-HFC-P and [(15)N]alanine to produce [(15)N] 5-(aminomethyl)-3-furanmethanol-P (F1-P) and pyruvate. To confirm these results in cell extracts, we developed sensitive analytical methods for the liquid chromatography-ultraviolet-electrospray ionization mass spectrometry analysis of F1 as a 7-nitrobenzofurazan derivative. This method has allowed for the quantitation of trace amounts of F1 and F1-P in cell extracts and the measurement of the incorporation of stable isotopically labeled precursors into F1. After incubation of cell extracts with [1,2,3-(13)C3]pyruvate and DHAP, 4-([(2)H2]hydroxymethyl)-2-furancarboxylic acid phosphate (4-HFCA-P) or 4-([(2)H2]hydroxymethyl)-2-furancarboxaldehyde phosphate (4-HFC-P) was found to be incorporated into F1-P. 4-HFCA-P and 4-HFC-P were confirmed in cell extracts after removal of the phosphate. The low level of incorporation of [1,2,3-(13)C3]pyruvate into F1-P in these experiments is explained by the fact that the labeled pyruvate must first be converted into Ga-3-P through gluconeogenesis before being incorporated into 4-HFC-P. Cell extracts incubated with 4-HFC-P and a mixture of [(15)N]aspartate, [(15)N]glutamate, and [(15)N]alanine produced [(15)N]F1-P. We also demonstrated that aqueous solutions of methylglyoxal or pyruvate heated with dihydroxyacetone led to the formation of 4-HFC and 4-HFCA, suggesting a possible prebiotic route to this moiety of methanofuran.
