The psychrophile Clostridium sp. strain 69 contains a thermolabile triose phosphate isomerase which is inactivated rapidly in vitro and in vivo at 32 C.

In this study, phosphoenolpyruvate and erythrose-4-phosphate are efficiently supplied by collaborative design of Embden-Meyerhof-Parnas (EMP) pathway pentose phosphate (PP) in Escherichia coli, thus increasing the L-tryptophan production. Firstly, effects disrupting EMP on production were studied, results indicated that strain with deletion phosphofructokinase A (i.e., E. coli JW-5 ΔpfkA) produ...

The enzyme profiles of 109 Bolivian stocks of Trypanosoma cruzi were determined by cellulose acetate electrophoresis using the four enzymes: malate dehydrogenase (oxaloacetate decarboxylating) (NADP+) (E.C.1.1.1.40, ME), phosphogluconate dehydrogenase (E.C.1.1.1.44, 6PGDH), phosphoglucomutase (E.C.2.7.5.1, PGM) and glucosephosphate isomerase (E.C.5.3.1.9, GPI). As previously, two principal zymo...
