“…Controlling radical intermediates and thus catalysing and directing complex radical reactions is a central feature of S‐adensosylmethionine (SAM)‐dependent radical enzymes. We report ab initio and DFT calculations highlighting the specific influence of ion complexation, including Mg(2+), identified as a key catalytic component on radical stability and reaction control in 7‐carboxy‐7‐deazaguanine synthase (QueE). …”

“…Our data suggest that this intermediate is formed via a free radical reaction catalyzed by the radical S-adenosylmethionine (SAM) enzyme, PolH, and using 3′-enolpyruvyl uridine 5′-monophosphate (3′-EUMP) as a substrate. …”

“…All mitochondrial outer membrane channels known to date are β-barrel membrane proteins, including the abundant voltage-dependent anion channel and the cation-preferring protein-conducting channels Tom40, Sam50, and Mdm10. We analyzed outer membrane fractions of yeast mitochondria and identified four new channel activities: two anion-preferring channels and two cation-preferring channels. …”

“…Here we present the crystal structures of the Zika methyltransferase domain in complex with the methyl-donor SAM and its by-product SAH. The methyltransferase-SAH binary complex presents a new conformation of a “closed” or “obstructed” state that would restrict the binding of new RNA for capping. …”

“…Three genes are implicated in immunity, namely, tunI and tunJ, which encode a two-component ABC transporter presumably required for export of the antibiotic, and tunM, which encodes a putative S-adenosylmethionine (SAM)-dependent methyltransferase. Expression of tunIJ or tunM in S. coelicolor conferred resistance to exogenous tunicamycin. …”

In order to achieve a 5:1 ratio of the number of observations to predictors which is vital for an effective quantitative structure-activity relationship (QSAR) modelling, factor analysis was used to reduce the data. …”
