(9 nodes) Alpha amylase, catalytic domain network (Arabidopsis thaliana)

Nodes:

Network nodes represent proteins

splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.

Node Color

colored nodes:
query proteins and first shell of interactors

white nodes:
second shell of interactors

Node Content

empty nodes:
proteins of unknown 3D structure

filled nodes:
a 3D structure is known or predicted

Edges:

Edges represent protein-protein associations

associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

Known Interactions

from curated databases

experimentally determined

Predicted Interactions

gene neighborhood

gene fusions

gene co-occurrence

Others

textmining

co-expression

protein homology

Your Input:
	ISA2	Isoamylase 2, chloroplastic; Involved in the trimming of pre-amylopectin chains. Accelerates the crystallization of nascent amylopectin molecules during starch synthesis. ISA1 and ISA2 work exclusively together as a multimeric holoenzyme. ISA1-ISA2 removes preferentially branches that are very close to other branches. (882 aa)
	SBE3	1,4-alpha-glucan-branching enzyme 3, chloroplastic/amyloplastic; Catalyzes the formation of the alpha-1,6-glucosidic linkages in starch by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position. Essential during embryogenesis; Belongs to the glycosyl hydrolase 13 family. GlgB subfamily. (899 aa)
	ISA1	Isoamylase 1, chloroplastic; Involved in the trimming of pre-amylopectin chains. Accelerates the crystallization of nascent amylopectin molecules during starch synthesis. ISA1 and ISA2 work exclusively together as a multimeric holoenzyme. ISA1-ISA2 removes preferentially branches that are very close to other branches. (783 aa)
	SBE2.1	1,4-alpha-glucan-branching enzyme 2-1, chloroplastic/amyloplastic; Catalyzes the formation of the alpha-1,6-glucosidic linkages in starch by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position. Belongs to the glycosyl hydrolase 13 family. GlgB subfamily. (858 aa)
	AMY2	Probable alpha-amylase 2; Probable alpha-amylase that does not seem to be required for breakdown of transitory starch in leaves. (413 aa)
	AMY1	Alpha-amylase 1; Possesses alpha-amylase activity in vitro, but seems not required for breakdown of transitory starch in leaves. (423 aa)
	AMY3	Alpha-amylase 3, chloroplastic; Possesses endoamylolytic activity in vitro, but seems not required for breakdown of transitory starch in leaves. May be involved in the determination of the final structure of glucans by shortening long linear phospho-oligosaccharides in the chloroplast stroma. Can act on both soluble and insoluble glucan substrates to release small linear and branched malto-oligosaccharides. Works synergistically with beta-amylase toward efficient starch degradation. Has activity against p-nitrophenyl maltoheptaoside (BPNP-G7), amylopectin and beta-limit dextrin. Involv [...] (887 aa)
	SBE2.2	1,4-alpha-glucan-branching enzyme 2-2, chloroplastic/amyloplastic; Catalyzes the formation of the alpha-1,6-glucosidic linkages in starch by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position. Belongs to the glycosyl hydrolase 13 family. GlgB subfamily. (805 aa)
	ISA3	Isoamylase 3, chloroplastic; Involved in starch catabolism. ISA3 removes different branches than ISA1-ISA2, namely short chains that prevent amylopectin crystallization. May be the debranching enzyme required to assist beta- amylases for starch degradation in leaves at night. Belongs to the glycosyl hydrolase 13 family. (764 aa)
