May regulate leaf (and possibly other organ) development by functioning in cell wall loosening and cell wall expansion. Hydrolysis of terminal, non-reducing alpha-D-galactose residues in alpha-D-galactosides, including galactose oligosaccharides, galactomannans and galactolipids. Homodimer. By Verticillium longisporum (VL43), in apoplasm. Increased rosette leaves number with a curly surface leaf morphology and delayed flowering. Belongs to the glycosyl hydrolase 27 family.
