High pressure near infrared study of the mutated light-harvesting complex LH2
Autor: Braun P., Gebhardt R., Kwa L., Doster W.
Publikováno v: Brazilian Journal of Medical and Biological Research, Vol 38, Iss 8, Pp 1273-1278 (2005)
The pressure sensitivities of the near infrared spectra of the light-harvesting (LH2) complex and a mutant complex with a simplified BChl-B850 binding pocket were compared. In the mutant an abrupt change in the spectral properties occurred at 250 MPa
