Thermostable chimeric PQQ glucose dehydrogenase [PDF]

FEBS Letters, 1995
The thermal stability of PQQ glucose dehydrogenases (PQQGDHs) which were chimeras with more than 95% made up of the N‐terminal region of Escherichia coli PQQGDH and the rest made up of the C‐terminal region of Acinetobacter calcoaceticus PQQGDHswas investigated. Among the chimeric PQQGDHs, E97A3 (E. coli 97% and A.

Information disclosure and questionnaires in public tenders

The Scandinavian Journal of Economics, EarlyView.
Abstract Public tenders typically involve uncertainty and unforeseen costs, which might not be fully known to the bidders themselves. This uncertainty may also concern adaptation costs to the procurer after the delivery, and information about such adaptation costs may influence the bidding strategies, even though the cost is paid by the procurer ...

Substrate‐Affinitive P‐Type Azapolycyclic Photosensitizer for Chemoselective Nitrilization Under Mild Conditions

Advanced Science, Volume 13, Issue 36, 29 June 2026.
We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...
