TīmeklisThe geometrical isomerism arises when atoms or groups are arranged differently in space due to restricted rotation of a bond or bonds in a molecule. E.g. 1) Two different spatial arrangements of methyl groups about a double bond in 2-butene give rise to the following geometrical isomers. i.e., cis-2-butene and trans-2-butene. TīmeklisThe final product of γ-l-glutamyl-l-β-ethynylserine (a dipeptide with an alkyne group) can also be synthesized by cell-free expression of the full biosynthetic pathway (i.e., five enzymes). Our results demonstrate the flexibility of cell-free systems, enabling easy regulation and rational optimization for target compound formation. iphone text message pew pew
