  • Title: [Biphasic nature of the light-dependent transport of C14-alanine into Halobacterium holobium cells].
    Author: Plakunova VG.
    Journal: Biofizika; 1976; 21(4):661-4. PubMed ID: 12838.
    Abstract:
    Biphase character of photoinduced pH change in H. halobium R1 suspension cells is shown: in the first illumination period pH rises and only afterwards it decreases. pH increase is accompanied by the introduction of C14-alanine into the cells, while the decrease by its yield up to the level lower than the "dark" one ("negative" photoeffect). The bi-phase character of transport processes seems to be explained by the reversible character of light-dependent bacteriorodopsin proton pump in H. halobium R1 cells.
