Activating Compound | Comment | Organism | Structure |
---|---|---|---|
lysolecithin | aprrox. 0.3%, 150% activation of activity in chromatophore extracts | Rhodospirillum rubrum |
General Stability | Organism |
---|---|
solubilized membrane component is unstable loosing all activity when stored overnight at 4°C or -70°C, stable at -70°C in the presence of 0.025 mM NADP+ for several months, inactivation by refreezing after thawing | Rhodospirillum rubrum |
trypsinolysis is stimulated several fold by NADPH and NADP+, half-maximal stimulation with 0.001-0.002 mM NADPH and 0.002-0.003 mM NADP+, Mg2+ protects from NADP+ stimulated inactivation | Rhodospirillum rubrum |
