Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

open access: yesAdvanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

Biochemical characterization of an ATP-dependent DNA ligase from the hyperthermophilic crenarchaeon Sulfolobus shibatae

open access: yesExtremophiles, 2002
A gene encoding a putative ATP-dependent DNA ligase was identified in the genome of the hyperthermophilic archaeon Sulfolobus shibatae and expressed in Escherichia coli. The 601 amino acid recombinant polypeptide was a monomeric protein capable of strand joining on a singly nicked DNA substrate in the presence of ATP ( K(m)=34 micro mu) and a divalent ...

The α-thio and/or β-γ-hypophosphate analogs of ATP as cofactors of T4 DNA ligase

Bioorganic Chemistry, 2016
T4 DNA ligase is one of the most commonly used enzymes for in vitro molecular research and a useful model for testing the ligation mechanism of ATP-dependent DNA ligation. To better understand the influence of phosphate group modifications in the ligation process, a series of ATP analogs were tested as cofactors.

A sensitive ligase-based ATP electrochemical assay using molecular beacon-like DNA

Biosensors and Bioelectronics, 2010
A sensitive and selective ligase-based signal-on electrochemical sensing method for adenosine-5'-triphosphate (ATP) detection had been developed using molecular beacon (MB)-like DNA. In this method, the biotin-tagged MB-like DNA was self-assembled onto a gold electrode to form a stem-loop structure by means of facile gold-thiol chemistry, which ...
