Transaldolase is an enzyme of the non-oxidative phase of the pentose phosphate pathway. It catalyzes the reversible transfer of dihydroxyacetone from sedoheptulose 7-phosphate to glyceraldehyde 3-phosphate, giving rise to erythrose 4-phosphate and fructose 6-phosphate.
Transaldolase was identified as cross-reactive mould allergen in Cladosporium cladosporioides (Cla c 14) and Penicillium chrysogenum (Pen ch 35) [1]. These allergens showed cross-reactivity with the human enzyme.
Family-defining Pfam domains (at least one of these domains is present in each family member):
| Pfam domain | Pfam clan | ||
| PF00923 | Transaldolase/Fructose-6-phosphate aldolase | CL0036 | Common phosphate binding-site TIM barrel superfamily |
