Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

open access: yesEcological Entomology, EarlyView.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Investigating the molecular mechanisms underlying the anti‐CRISPR function of AcrIIA13b protein

open access: yesThe FEBS Journal, EarlyView.
Anti‐CRISPR protein AcrIIA13b inhibits CRISPR–Cas9 function by preventing target DNA engagement. The Cas9–sgRNA ribonucleoprotein (RNP) normally recognizes the protospacer adjacent motif (PAM) duplex to initiate DNA cleavage. AcrIIA13b binding to the PAM‐interacting WED–PI domain blocks this recognition, leaving the target DNA intact.

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

open access: yesThe FEBS Journal, EarlyView.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Insights into the catalytic mechanism of formate dehydrogenases from different microbial sources

open access: yesThe FEBS Journal, EarlyView.
This integrated study combines experimental enzyme kinetics with QM/MM simulations to map the catalytic mechanisms of four formate dehydrogenases at the atomic level. This approach reveals the key determinants of catalytic efficiency and guides the rational design of biocatalysts for effective CO2 reduction—a crucial step towards sustainable ...
