The compound CH3-CO-NH-C(C2H5)2-COOH was synthesized from the corresponding free amino acid. N-Acetyl-Cα,α-diethylglycine crystallizes in the monoclinic space group P21/c with a = 13.551(2)Å, b = 11.110(3)Å, c = 13.569(3)Å, β = 111.54(2)°, Z = 8 , D = 1.21 g/cm3. This structure was solved by direct methods and refined to R = 0.084. N-Acetyl-Cα,α-diethylglycine shows a fully extended conformation in its -N H-C(C2H5)2-CO- part.

Fully Extended Conformation

The octadecyl chain in the title compound, C33H47NOS, is in the `fully extended' conformation. A puckering analysis of the thiazine ring was performed. The molecules form micellar blocks in the crystal by intercalation of the extended octadecyl chains and association of the dihydro benzothiazine units through C—H...O hydrogen bonds. These blocks are associated through intercalation of the pendant phenyl groups which reside on the outer edges of each block.

Present Solution

AbstractRho-associated protein kinase 2 (ROCK2) is a membrane-anchored, long, flexible, multidomain, multifunctional protein. Its functions can be divided into two categories: membrane-proximal and membrane-distal. A recent study concluded that membrane-distal functions require the fully extended conformation, and this conclusion was supported by electron microscopy. The present solution small-angle X-ray scattering (SAXS) study revealed that ROCK2 population is a dynamic mixture of folded and partially extended conformers. Binding of RhoA to the coiled-coil domain shifts the equilibrium towards the partially extended state. Enzyme activity measurements suggest that the binding of natural protein substrates to the kinase domain breaks up the interaction between the N-terminal kinase and C-terminal regulatory domains, but smaller substrate analogues do not. The present study reveals the dynamic behaviour of this long, dimeric molecule in solution, and our structural model provides a mechanistic explanation for a set of membrane-proximal functions while allowing for the existence of an extended conformation in the case of membrane-distal functions.
