Secret Talents: STARCH SYNTHASE 5—Not an Enzyme, but Very Active!
Abt et al. found that Arabidopsis SS5, a protein homologous to typical starch-synthesizing enzymes, is itself enzymatically inactive, but rather has an important role in the starch granule initiation process. Plant Cell https://doi.org/10.1105/tpc.19.00946
