dc.description.abstract | An enzyme with polySia degrading activity was purified from a culture filtrate of Pseudomonas fluorescens JK-0412 to apparent homogeneity using DEAE-Sepharose CL-6B column chomatography and fast performance liquid chomatography separation on a Mono-Q column. The molecular mass of the purified enzyme (tentatively named Endo-PS) was approximately 20 kDa on SDS-PAGE and 120 kDa on native-PAGE gels, suggesting that the active form is a hexamer. Although 12 residues of the Endo-PS N-terminal amino acid sequence showed 75% homology to the 21 kDa chitin binding protein (CBP21) of Serratia marcescens 2170, no significant similarity to other known proteins was observed. Apparent K (m) and V (max) values of Endo-PS toward the artificial substrate 4-methylumbelliferyl-sialic acid (4-MU-Neu5Ac) were 0.08 mM and 16 nmol/mg/min, respectively. The enzyme was maximally active at 37A degrees C and pH 8.0. Interestingly, the enzyme was shown to hydrolyze the natural substrate, alpha 2,8-linked polySia (colominic acid), in an endo-acting manner. However, no activity toward alpha 2,3- or alpha 2,6-sialyllactose was observed. Under optimal conditions, oligoSia ranging from 2 to 30 residues long were liberated by the cleavage of polySia, as identified by HPAEC-PED. Therefore, the purified enzyme Endo-PS was found to be a polySia-specific sialidase. This is the first report to describe the properties of a bacterial polySia-specific sialidase. Therefore, this enzyme may be a useful tool for both industrial oligoSia production and research on the structure and biological functions of polySia in nature. | - |
