Squalene-Hopene Cyclases [PDF]
Applied and Environmental Microbiology, 2011 ABSTRACTHopanoids and sterols are members of a large group of cyclic triterpenoic compounds that have important functions in many prokaryotic and eukaryotic organisms. They are biochemically synthesized from linear precursors (squalene, 2,3-oxidosqualene) in only one enzymatic step that is catalyzed by squalene-hopene cyclase (SHC) or oxidosqualene ...

Monospecific antibody against Bordetella pertussis Adenylate Cyclase protects from Pertussis [PDF]
Journal of Microbiology and Infectious Diseases, 2012 Objectives: Acellular pertussis vaccines has been largely accepted world-wide however, there are reports about limitedantibody response against these vaccines suggesting that multiple antigens should be included in acellular vaccinesto attain full ...

Structural basis of retinal membrane guanylate cyclase regulation by GCAP1 and RD3
Frontiers in Molecular Neuroscience, 2022 Retinal membrane guanylate cyclases (RetGC1 and RetGC2) are expressed in photoreceptor rod and cone cells, where they promote the onset of visual recovery during phototransduction.

Event Timing in Associative Learning [PDF]
, 2012 Associative learning relies on event timing. Fruit flies for example, once trained with an odour that precedes electric shock, subsequently avoid this odour (punishment learning); if, on the other hand the odour follows the shock during training, it is ...

Squalene cyclase and oxidosqualene cyclase from a fern [PDF]
FEBS Letters, 2007 Ferns are the most primitive vascular plants. The phytosterols of ferns are the same as those of higher plants, but they produce characteristic triterpenes. The most distinct feature is the lack of oxygen functionality at C‐3, suggesting that the triterpenes of ferns may be biosynthesized by direct cyclization of squalene.

Overexpression of the type 1 adenylyl cyclase in the forebrain leads to deficits of behavioral inhibition [PDF]
, 2015 The type 1 adenylyl cyclase (AC1) is an activity-dependent, calcium-stimulated adenylyl cyclase expressed in the nervous system that is implicated in memory formation. We examined the locomotor activity, and impulsive and social behaviors of AC1+ mice, a

Chemo- and Thermosensory Responsiveness of Grueneberg Ganglion Neurons Relies on Cyclic Guanosine Monophosphate Signaling Elements [PDF]
, 2011 Neurons of the Grueneberg ganglion (GG) in the anterior nasal region of mouse pups respond to cool temperatures and to a small set of odorants. While the thermosensory reactivity appears to be mediated by elements of a cyclic guanosine monophosphate ...
