CGR3

Gene
CGR3
Protein
Probable pectin methylesterase CGR3
Organism
Arabidopsis thaliana
Length
258 amino acids
Function
Together with CGR2, required for homogalacturonan pectins (HG) methylesterification in the Golgi apparatus prior to integration into cell walls, essential for general growth and development (PubMed:21422118, PubMed:25704846, PubMed:27208234). Promotes petiole elongation (PubMed:21422118). Impacts photosynthesis and respiration efficiency by influencing leaf mesophyll morphology and physiology; pectin methylesterification modulates both expansion and positioning of cells in leaves, probably by changing cell walls plasticity (PubMed:27208234).
Similarity
Belongs to the class I-like SAM-binding methyltransferase superfamily.
Mass
28.296 kDa
