Two triphosphate tunnel metalloenzymes from apple exhibit adenylyl cyclase activity

open access: yesFrontiers in Plant Science, 2022
Adenylyl cyclase (AC) is the key catalytic enzyme for the synthesis of 3′,5′-cyclic adenosine monophosphate. Various ACs have been identified in microorganisms and mammals, but studies on plant ACs are still limited.

Reducing Ensembles of Protein Tertiary Structures Generated De Novo via Clustering

open access: yesMolecules, 2020
Controlling the quality of tertiary structures computed for a protein molecule remains a central challenge in de-novo protein structure prediction. The rule of thumb is to generate as many structures as can be afforded, effectively acknowledging that ...

Disruption of the C-terminal helix by single amino acid deletion is directly responsible for impaired cholesterol efflux ability of apolipoprotein A-I Nichinan

open access: yesJournal of Lipid Research, 2010
Apolipoprotein A-I (apoA-I) Nichinan, a naturally occurring variant with ΔE235 in the C terminus, is associated with low plasma HDL levels. Here, we investigated the tertiary structure, lipid-binding properties, and ability to induce cellular cholesterol
