Expansin family protein
WebOct 25, 2024 · Expansin family proteins contain an N-terminal domain (D1) homologous to the catalytic domain of glycoside hydrolase family 45 (GH45) proteins but with no hydrolytic activity, and a C-terminal domain (D2) homologous to group-2 grass pollen allergens. This family also includes GH45 endoglucanases from mollusks. Expansins are a family of closely related nonenzymatic proteins found in the plant cell wall, with important roles in plant cell growth, fruit softening, abscission, emergence of root hairs, pollen tube invasion of the stigma and style, meristem function, and other developmental processes where cell wall … See more So far, two large families of expansin genes have been discovered in plants, named alpha-expansins (given the gene symbol EXPA) and beta-expansins (EXPB). Both families of expansins have been identified in a … See more The plant cell wall has high tensile strength and must be loosened to enable the cell to grow (enlarge irreversibly). Within the cell wall, this expansion of surface area involves slippage or movement of cellulose microfibrils, which normally is coupled to … See more • Cellulose • Plant cell wall • Acid growth See more Expansins characteristically cause wall stress relaxation and irreversible wall extension (wall creep). This process is essential for cell enlargement. Expansins are also expressed … See more Expansins are proteins; the two expansins initially uncovered had molecular weights of 29 kDa (kiloDalton) and 30 kDa, which would correspond to around 270 amino acids on average. Generally speaking, α- and β-expansins and expansin-like are composed of … See more In grass pollens, the major allergens (group-1 allergens, main causative agents of hay fever and of seasonal asthma) are structurally linked … See more
