Arabidopsis	At1g03310	Involved in the trimming of pre-amylopectin chains.	Arabidopsis mutants Atisa1 and Atisa2 have identical phenotypes and lack the same multimeric isoamylase, which influences the branch point distribution of amylopectin during starch synthesis.; 2005; DOI: 10.1111/j.1365-313x.2005.02348.x; PMID: 15743447; https://pubmed.ncbi.nlm.nih.gov/15743447/ | Further evidence for the mandatory nature of polysaccharide debranching for the aggregation of semicrystalline starch and for overlapping functions of debranching enzymes in Arabidopsis leaves.; 2008; DOI: 10.1104/pp.108.129379; PMID: 18815382; https://pubmed.ncbi.nlm.nih.gov/18815382/ | Starch granule biosynthesis in Arabidopsis is abolished by removal of all debranching enzymes but restored by the subsequent removal of an endoamylase.; 2008; DOI: 10.1105/tpc.108.063487; PMID: 19074683; https://pubmed.ncbi.nlm.nih.gov/19074683/
Arabidopsis	At4g09020	Involved in starch catabolism.
