DTT sensitivity of C. reinhardtii
isoamylases. The fresh crude extracts from synchronized cultures were
used to assay isoamylase activities in wild-type and sta8
strains using bovine liver glycogen as substrate (see “Materials and
Methods”) at various DTT concentrations. Results are displayed as
nanomoles of maltotriose formed by hour and per milligram of protein.
The x axis represents the DTT concentrations used in the
incubation buffer. Means (●, ▪, ○ for wild-type [330],
sta8-1::ARG7 [BafV13],
sta7-4::ARG7 [Bafj6] strains, respectively) and
sd from three distinct measures were calculated
for each DTT concentration.
