Squalene-hopene cyclase, which catalyzes the complex cyclization of squalene to the pentacyclic triterpene, hopene, is a key enzyme in the biosynthesis of hopanoids. The deduced amino acid sequence of the Streptomyces peucetius gene (spterp25) had significant similarity to other prokaryotic

To provide insight into the polycyclization mechanism of squalene by squalene-hopene cyclase (SHC) from Alicyclobacilus acidocaldarius, some analogs of nor- and bisnorsqualenes were synthesized including the deuterium-labeled squalenes and incubated with the wild-type SHC, leading to the following inferences.

The long-standing question of what is the nature of the cyclization of squalene to form tetracyclic and pentacyclic triterpenes has been addressed computationally. Using the DFT method with an intrinsic reaction coordinate calculation, we find that the first three rings

The analysis of biochemical processes is one of the main challenges for modern computational chemistry. Probably the biggest issue facing scientists in this case is the number of factors that have to be taken into account, as even those factors
T Sato et al.
Bioscience, biotechnology, and biochemistry, 62(2), 407-411 (1998-04-09)
An overexpression system for squalene-hopene cyclase (SHC) was constructed by using the pET3a vector, which is responsible for high expression with help from the strong T7 promoter when incorporated into E. coli BL21(DE3). Site-directed mutagenesis experiments prove that two amino

What can I expected for 'limited shelf life'? Is this in the order of weeks, months, years?
