One such pathway is the fucose-utilization pathway, a component of which is fucose mutarotase (SpFcsU), an enzyme that performs the interconversion between alpha-L-fucose and beta-L-fucose. This protein was crystallized and its three-dimensional structure was solved in complex with L-fucose. The structure shows a complex decameric quaternary structure with a high overall degree of structural identity to Escherichia coli FcsU (EcFcsU). Furthermore, the active-site architecture of SpFcsU is highly similar to that of EcFcsU. When considered in the context of the fucose-utilization pathway found in S. pneumoniae, SpFcsU appears to link the two halves of the pathway by enhancing the rate of conversion of the product of the final glycoside hydrolysis step, beta-fucose, into the substrate for the fucose isomerase, alpha-fucose.
