Manipulating the self-assembly pathway is essentially important in the supramolecular synthesis of organic nano- and micro-architectures. Here we design a series of photoisomerizable chiral molecules, and realize the precise control over pathway complexity with external light stimuli. The hidden single-handed microcoils, rather than the straight microribbons via spontaneous assembly, are obtained through the kinetics-controlled pathway. The competition between molecular interactions in metastable photostationary intermediates gives rise to the variety of molecular packing and thereby the possibility of chirality transfer from molecules to supramolecular assemblies.

Polymers of N-SUBSTITUTED GLYCINES containing chiral centers at the a-position of their side chains. These oligomers lack HYDROGEN BONDING donors, preventing formation of the usual intrachain hydrogen bonds but can form helices driven by the steric influence of chiral side chains.
Complement activation triggered by the interaction of microbial POLYSACCHARIDES with serum MANNOSE-BINDING LECTIN resulting in the activation of MANNOSE-BINDING PROTEIN-ASSOCIATED SERINE PROTEASES. As in the classical pathway, MASPs cleave COMPLEMENT C4 and COMPLEMENT C2 to form C3 CONVERTASE (C4B2A) and the subsequent C5 CONVERTASE (C4B2A3B) leading to cleavage of COMPLEMENT C5 and assembly of COMPLEMENT MEMBRANE ATTACK COMPLEX.
A GTP-BINDING PROTEIN involved in regulating a signal transduction pathway that controls assembly of focal adhesions and actin stress fibers. This enzyme was formerly listed as EC 184.108.40.206.
