Zn(II) coordination influences the secondary structure, but not antimicrobial activity of the N-terminal histatin 3 hydrolysis product

Dalton Trans., 2024, Advance Article
DOI: 10.1039/D4DT02274B, Paper
Emilia Dzień, Joanna Wątły, Aleksandra Hecel, Aleksandra Mikołajczyk, Agnieszka Matera-Witkiewicz, Miquel Adrover, Miquel Barceló-Oliver, Alicia Domínguez-Martín, Magdalena Rowińska-Żyrek
Histatin 3 and 4 have greater activity against Gram(+) than Gram(−) bacteria, and Cu(II) or Zn(II) binding can moderately increase their antimicrobial activity. The N-terminal part of histatin 3 becomes α-helical upon Zn(II) binding.
