C81S | mutation in small subunit APS1. Substitution of Cys81 by serine prevents small subunit APS1 dimerization. Cys81 is both necessary and sufficient for dimerization of APS1. Compared to control plants, the C81S lines have higher levels of ADP-glucose and maltose, and either increased rates of starch synthesis or a starch-excess phenotype, depending on the daylength. APS1 protein levels are five- to tenfold lower than in control plants | Arabidopsis thaliana |
additional information | complementation of an aps1 null mutant with a series of constructs containing a full-length APS1 gene encoding either the wild-type APS1 protein or mutated forms in which one of the five cysteine residues is replaced by serine. Substitution of Cys81 by serine prevents small subunit APS1 dimerization, whereas mutation of the other cysteines had no effect | Arabidopsis thaliana |
