We develop an algorithm for meshing molecular surfaces that is based on patch-wise meshing using an advancing-front method adapted to the particular case of molecular surfaces. We focus on the solvent accessible surface (SAS) and the solvent excluded surface (SES). The essential ingredient is a newly developed analysis of such surfaces in [18] that allows to describe all SES-singularities a priori and therefore a complete characterization of the SES. In addition, an algorithm for filling molecular inner holes is proposed based on the pre-computed data structures of molecular surfaces.

Cryo-EM analysis of complement C3 reveals a reversible major opening of the macroglobulin ring.

The C3 protein is the central molecule within the complement system and undergoes proteolytic activation to C3b in the presence of pathogens. Pattern-independent activation of C3 also occurs via hydrolysis, resulting in C3(HO), but the structural details of C3 hydrolysis remain elusive. Here we show that the conformation of the C3(HO) analog, C3MA, is indistinguishable from C3b.

The sluggish water oxidation reaction (WOR) is considered the kinetic bottleneck of artificial photosynthesis due to the complicated four-electron and four-proton transfer process. Herein, we find that the WOR can be kinetically nearly barrierless on four representative photoanodes (i.e.

Molds are persistent and harmful but receive far less research attention compared with pathogenic bacteria. With the increase in microbial resistance to single-chain surfactant antimicrobial agents, it is crucial to investigate how surfactant structures affect the antimicrobial activity of surfactants. Here, we have studied the antimold efficacy of a series of oligomeric cationic quaternary ammonium surfactants at varying oligomerization levels with or without dynamic covalent imine bonds.
