In an article, author is Balkenhohl, Moritz, once mentioned the application of 33208-99-0, Application In Synthesis of H-Ala-NH2.HCl, Name is H-Ala-NH2.HCl, molecular formula is C3H9ClN2O, molecular weight is 124.57, MDL number is MFCD00066145, category is amides-buliding-blocks. Now introduce a scientific discovery about this category.
Membrane proteins are universal signal decoders. The helical transmembrane segments of these proteins play central roles in sensory transduction, yet the mechanistic contributions of secondary structure remain unresolved. To investigate the role of main-chain hydrogen bonding on transmembrane function, we encoded amide-to-ester substitutions at sites throughout the S4 voltage-sensing segment of Shaker potassium channels, a region that undergoes rapid, voltage-driven movement during channel gating. Functional measurements of ester-harboring channels highlight a transitional region between alpha-helical and 3(10) segments where hydrogen bond removal is particularly disruptive to voltage-gating. Simulations of an active voltage sensor reveal that this region features a dynamic hydrogen bonding pattern and that its helical structure is reliant upon amide support. Overall, the data highlight the specialized role of main-chain chemistry in the mechanism of voltage-sensing; other catalytic transmembrane segments may enlist similar strategies in signal transduction mechanisms.
