molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile
A systematic understanding of gelation self-assembly: solvophobically assisted supramolecular gelation via conformational reorientation across amide functionality on a hydrophobically modulated dipeptide based ambidextrous gelator, N-n-acyl-(<scp>l</scp>)Val-X(OBn), (X = 1,ω-amino acid)

Gelator backbone conformational flexibility plays an important role in a supramolecular self-assembly which is synergistically assisted by solvophobic interaction leading to a gelation of three sets of hydrophobically modulated dipeptidic gelators.
An object of the present invention is to provide a moisturizer that can sufficiently promote the production of moisturizing-related proteins and can achieve sufficient moisturizing effect. In other words, the present invention provides a moisturizer including an acyl neutral amino acid involving an acyl group having a carbon atom number of 2 to 18 or a salt thereof, and a cosmetic including the moisturizer. The moisturizer and the cosmetic of the present invention can promote the production of one or more moisturizing-related proteins selected from the group consisting of filaggrin, involucrin, transglutaminase 1, keratin 10, and loricrin.
Moisturizers including an acyl neutral amino acid having an acyl group with a carbon atom number of 2 to 18, and salts thereof, and cosmetics containing such a moisturizer promote the production of moisturizing-related proteins, such as filaggrin, involucrin, transglutaminase 1, keratin 10, and loricrin, and provide a moisturizing effect.
