    Methylation at the C-2 position of hopanoids increases rigidity in native bacterial membranes

    Chia-Hung Wu et al.
    Methylation specifically enhances the ability of hopanoids to rigidify membranes under physiologically relevant conditions, which impacts the current interpretation of the 2-methylhopane fossil record.

    Regulation by the quorum sensor from Vibrio indicates a receptor function for the membrane anchors of adenylate cyclases

    Stephanie Beltz et al.
    A canonical class III adenylate cyclase with a membrane anchor of six transmembrane spans is regulated by a receptor of similar design, the quorum-sensing receptor from Vibrio harveyi.

    Differing isoforms of the cobalamin binding photoreceptor AerR oppositely regulate photosystem expression

    Haruki Yamamoto et al.
    A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.
