Filaments dubbed \"cytochrome nanowires\" (CNs) have been resolved by CryoEM, but whether they are the two-decades-long sought-after physiological \"nanowires\" remains unproven. To assess their functional competence, we analyzed biological redox conduction in all CNs by computing driving forces in the presence of redox anti-cooperativities, reorganization energies with electronic polarizability, and Marcus rates for diffusive and protein-limited flux models. The chain of heme cofactors in any CN must be densely packed to realize weak (≤0.01 eV) electronic coupling for electron transfer, as evidenced by a single Soret band produced from coincidental absorptions on multiple hemes. Dense packing, in turn, has three consequences: (1) limited driving forces (≤|0.3| eV) due to shared electrostatic microenvironments, (2) strong (≤0.12 eV) redox anti-cooperativities that would accentuate the free energy landscape if the linear heme arrangement did not dictate a contra-thermodynamic oxidation order, and (3) an entropic penalty that is offset by thioether 'tethers' of the hemes to the protein backbone. These linkages physically necessitate the rate-throttling T-stacked motif (10-fold slower than the other highly conserved slip-stacked motif). If the sequence of slip- and T-stacked hemes in the CNs had the fastest known nanosecond rates at every step, a micron-long filament would carry a diffusive 0.02 pA current at a physiological 0.1 V, or a protein-limited current of 0.2 pA. Actual CNs have sub-optimal (≤10<sup>2</sup>-fold lower), but sufficient conductivities for cellular respiration, with at most thousands of filaments needed for total cellular metabolic flux.

The greatest increase in TPC was seen in cultures treated with 25 µM of salicylic acid (SA<sub>2</sub>), recording 336.80 ± 8.35 mg/100 g dry weight (DW), and in cultures treated with 100 mg/mL of chitosan (CHT<sub>5</sub>), which showed 325.74 ± 7.81 mg/100 g DW. Among individual phenolics, kaempferol showed a remarkable increase under SA<sub>2</sub> (192.82 ± 17.99 mg/100 g DW) compared to the control (103.68 ± 5.00 mg/100 g DW), and CHT<sub>5</sub> treatment (119.68 ± 12.01 mg/100 g DW). Additionally, rutin accumulation peaked at 30.64 ± 3.00 mg/100 g DW under SA<sub>2</sub> treatment. Antioxidant activities, measured by DPPH and TAC assays, were also enhanced, with SA<sub>2</sub> and CHT<sub>5</sub> treatments showing significant improvement over the control. The SA<sub>2</sub>-elicited cultures exhibited superior anti-tyrosinase and anti-elastase activities, with IC<sub>50</sub> values of 51.43 ± 1.31 μg/mL, 35.42 ± 4.42 μg/mL, and 31.84 ± 0.60 μg/mL, respectively. These findings suggest that elicitors effectively boost the bioactive compound production in <i>P. graveolens</i> calli, and subsequently the biological activity, highlighting their potential in developing natural skincare products with antioxidant and anti-aging benefits.</p>","PeriodicalId":12421,"journal":{"name":"Frontiers in Chemistry","volume":"13 ","pages":"1537877"},"PeriodicalIF":3.8,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11925866/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143691543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
