The storage capacity of underground gas storages in the Czech republic [PDF]

open access: yes, 2019
Sources of natural gas are in most cases located in remote areas far from the places where the gas is utilized, i.e. especially developed industrial countries to which it is transported via pipeline. However, transit gas pipelines, which are transporting

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These
