Abstract
The complementary deoxyribonucleic acid (cDNA) coding spinach glycolate oxidase (GO) was amplified by reverse transcription polymerase chain reaction (RT-PCR), using the total ribonucleic acid (RNA) of spinach leaves as the template, and was cloned into cloning vector pMD18-T. After the DNA sequence was determined, the go gene was subcloned into Escherichia coli expression vectors. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed that recombinant GO was expressed in E. coli BL21 (DE3)(pTIG-Trx-GO) and E. coli BL21 (DE3)(pET-22b(+)-GO). The result of the enzyme activity assay and the oxidation of glycolate to glyoxylate catalyzed by the whole cells of E. coli BL21 (DE3)(pET-22b(+)-GO) proved the feasibility of using E. coli cells to produce glyoxylic acid.Keywords
