Revisiting the nutritional advantages of plant-based food matrices: a systematic review on the influence of spontaneous fermentation (2025)
Atuna, Richard A. ; Akabanda, Fortune ; Andrade Laborde, Juan E. ; Makurat, Jan ; Bordewick-Dell, Ursula ; Lamping, Matthias ; Ritter, Guido
This systematic review critically examines existing literature on the effects of spontaneous fermentation on the nutritional and antinutritional properties of the aforementioned food staples, focusing on the changes in nutrients, digestibility, and antinutrients. The literature search flow was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRiSMA-2020) approach. Only peer-reviewed journal articles published in English between 2002 and 2024 were sourced from Scopus, Web of Science, and PubMed. A total of 67 articles were considered eligible after the title, abstract, full text, and quality assessment. It was evident from the various studies consulted in this review that traditional fermentation, though being an ancient food processing practice, remains an important approach for increasing the level of nutrients, reducing antinutritional factors, and enhancing the nutrient digestibility of cereals, legumes, roots, tuber, and plantain. This has made fermented foods an important part of diet and nutrition in many cultures around the world, especially in the global south, with limited access to sophisticated food processing techniques and infrastructure. Overall, the findings suggest that incorporating spontaneous fermentation into the preparation of cereals, legumes, roots, and tuber crops can be a valuable strategy for enhancing the nutritional value and health-promoting properties of these dietary staples.

Inverse γ-Turn-Inspired Peptide: Synthesis and Analysis of Segetalin A Indole Hemiaminal (2015)
Lamping, Matthias ; Enck, Sebastian ; Geyer, Armin
Substitution of a peptide bond for an imine transforms the irreversible macrocyclization of peptides into a reversible process. The inherent cyclization tendency of a linear peptide is then analyzable through the equilibrium between the aldehyde and the imine by virtue of the higher reactivity of the corresponding linear peptide aldehyde. The tryptophan side chain of segetalin A aldehyde forms a 12‐membered cyclic indole hemiaminal instead of the 18‐membered macrocyclic imine expected. Herein, we analyzed this uncommon hemiaminal that shows that the biosynthesis of cyclic peptides is not necessarily based on linear precursor peptides with a high inherent macrolactamization tendency.
Synthesis and conformational analysis of an expanded cyclic ketoxime-hexapeptide (2016)
Lamping, Matthias ; Grell, Yvonne ; Geyer, Armin
n this work the synthesis of a linear hexapeptide with a hydroxylamine functionality at the N‐terminus and a ketone instead of the carboxylic acid at the C‐terminus is described. Cyclization by ketoxime formation yields the 19‐membered ring‐expanded cyclic hexapeptide cyclo[Goly‐Val‐Ala‐Pro‐Leu‐Kly] which adopts a main conformer with two intramolecular hydrogen bonds. The hydrolytic stability of a ketoxime lies between the inert amide and the labile imine. The substitution of an amide bond for an iminium bond transforms the irreversible macrocyclization into a reversible process, but macrocyclic imines are difficult to isolate because they are prone to hydrolysis. The enhanced chemical stability of the ketoxime justifies its application in ligation protocols. The detailed NMR analysis of a ketoxime linkage presented here identifies its local conformational preferences in a constrained peptide environment.
Synthesis of a biological active β-hairpin peptide by addition of two structural motifs (2017)
Fischer, Sabrina ; Lamping, Matthias ; Gold, Maike ; Röttger, Yvonne ; Brödje, Dörte ; Dodel, Richard ; Frantz, Renate ; Mraheil, Mobarak Abu ; Chakraborty, Trinad ; Geyer, Armin
The idea of privileged scaffolds – that there seem to be more bioactive compounds found around some structures than others – is well established for small drug molecules, but has little significance for standalone peptide secondary structures whose adaptable shapes escape the definition of a 3D motif in the absence of a protein scaffold. Here, we joined two independent biological functions in a single highly restricted peptide to support the hypothesis that the β-hairpin shape is the common basis of two otherwise unrelated biological recognition processes. To achieve this, the hydrophobic cluster HWX4LV from the decapeptide cyclic hairpin model peptide C1-C10 cyclo-CHWEGNKLVC was included in the bicyclic peptide 2. The designed β-hairpin peptide C4-C17, C8-C13 bicyclo-KHQCHWECTZGRCRLVCGRSGS (2, Z = citrulline), serves, on the one hand, as a specific epitope for rheumatoid autoantibodies and, on the other hand, shows a not negligible antibiotic effect against the bacterial strain E. coli AS19.
Light-Driven Chloride Transport Kinetics of Halorhodopsin (2018)
Feroz, Hasin ; Ferlez, Bryan ; Lefoulon, Cecile ; Ren, Tingwei ; Baker, Carol S. ; Gajewski, John P. ; Lugar, Daniel J. ; Gaudana, Sandeep B. ; Butler, Peter J. ; Hühn, Jonas ; Lamping, Matthias ; Parak, Wolfgang J. ; Hibberd, Julian M. ; Kerfeld, Cheryl A. ; Smirnoff, Nicholas ; Blatt, Michael R. ; Golbeck, John H. ; Kumar, Manish
Despite growing interest in light-driven ion pumps for use in optogenetics, current estimates of their transport rates span two orders of magnitude due to challenges in measuring slow transport processes and determining protein concentration and/or orientation in membranes in vitro. In this study, we report, to our knowledge, the first direct quantitative measurement of light-driven Cl− transport rates of the anion pump halorohodopsin from Natronomonas pharaonis (NpHR). We used light-interfaced voltage clamp measurements on NpHR-expressing oocytes to obtain a transport rate of 219 (± 98) Cl−/protein/s for a photon flux of 630 photons/protein/s. The measurement is consistent with the literature-reported quantum efficiency of ∼30% for NpHR, i.e., 0.3 isomerizations per photon absorbed. To reconcile our measurements with an earlier-reported 20 ms rate-limiting step, or 35 turnovers/protein/s, we conducted, to our knowledge, novel consecutive single-turnover flash experiments that demonstrate that under continuous illumination, NpHR bypasses this step in the photocycle.
