In kinetics experiments, the hydrolysis of the substrate sialic acid by neuraminidase appears to obey michaelis–menten kinetics. neuraminidase activity is critical for viral infectivity; thus, this enzyme is the target of much work by pharmaceutical companies to develop a drug to treat influenza virus infection. the drug "tamiflu" is a competitive inhibitor of neuraminidase. initial rate data collected at ph=6.15, 37 ∘c with 0.021 μm neuraminidase and 25.0 μm sialic acid gives a lineweaver–burk plot with a slope of 51.2 s. the kcat for neuraminidase at ph=6.15, 37 ∘c is 26.8 s−1. calculate km for the hydrolysis of sialic acid. express your answer with the appropriate units. km = ? value ? units
