1jop is a 4 chain structure with sequence from Haemophilus influenzae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
NANQ_HAEIN Opens both the alpha- and beta-forms of N-acetylneuraminate (sialic acid; Neu5Ac) to provide aceneuramate, the preferred substrate for NanA (Probable). Has preferential activity on the beta-anomer rather than the alpha-anomer. Accelerates a reaction that is spontaneous at slightly alkaline pH, facilitates the reaction at acidic pH (By similarity).[UniProtKB:P45424][1]
