Other claims from this paper (11)
- Association An inactivator protein from maize endosperm inactivates invertase I even in the presence of other proteins.
- Association The quantity of the inactivator increases in normal endosperm during development.
- Association Invertase I activity decreases in normal endosperm during development.
- Association Altered invertase I activity in several endosperm mutant lines does not result from different quantities of the inactivator.
- Association The inactivator can decrease invertase I activity during a preincubation period before sucrose is added.
- Observation Inactivation of invertase I by the inactivator is noncompetitive.
- Observation A latent period without inactivation of invertase I is observed at high buffer concentrations or low inactivator concentrations.
- Association Inactivation increases with an increase in temperature.
- Association Inactivation increases with a decrease in pH.
- Observation No inactivation of maize invertase II or yeast invertase was observed.
- Observation The inactivator and invertase I are found only in the endosperm of maize.
