    Sialidases, or neuraminidases, have been implicated in the pathogenesis of many diseases, but are also produced by many non-pathogenic bacteria. Bacterial sialidases are very variable in size, often possessing domains in addition to the catalytic domain. The sialidase from the non-pathogenic soil bacterium Micromonospora viridifaciens is secreted in two forms with molecular weights of 41 kDa or 68 kDa, depending on the nature of the carbohydrate used to induce expression.
