Membrane-bound 5'-nucleotidase in marine luminous bacteria: biochemical and immunological properties.
A novel 5'-nucleotidase previously described in halophilic Vibrio costicola was detected in marine Vibrio and Photobacterium strains. The enzyme of marine bacteria was similar in its properties to the 5'-nucleotidase of Vibrio costicola; it was outwardly oriented in the cytoplasmic membrane and dephosphorylated nucleoside 5'-tri-, di-, and mono-phosphates to respective nucleosides before uptake. The enzyme in marine strains was immunologically cross-reactive with the antibody raised against the purified 5'-nucleotidase of Vibrio costicola. The uptake of the products of ATP hydrolysis was studied in Vibrio harveyi, and it was shown that both adenosine and inorganic phosphate released upon the action of 5'-nucleotidase were rapidly taken up by the cell.
