Abstract The purine nucleoside phosphorylas (PNP,EC.2.4.2.1) genes deoD and punA which amplified from the Bacillus subtilis168 genome by polymerase chain reaction were identified, cloned and expressed in E. coli XL-Blue, respectively. Recombinant purine nucleoside phosphorylases PNP702 and PNP816 were purified by Ni+-NTA column, and several characteristics were determined. The results revealed that PNP702 and PNP816 both have the same optimal temperature (60℃) and pH (7~8). Enzymic kinetics experiment showed that the catalytic efficiency (Kcat/Km) of PNP816 is 11.12 times higher than that of PNP702 toward inosine. Compared with PNP816, PNP702 has broader substrate specificity. The engineering strain XL-Blue (pPNP816) has much higher catalytic activity than the XL-Blue (pPNP702) in enzymatic synthesizing of the nucleoside antiviral drugs ribavirin, indicating that the low molecular weight homologous trimer PNP derived from microorganisms has the same or higher value in the microbial enzymatic synthesis of nucleoside drugs and intermediates.
