(1) functions as a sunscreen, absorbing harmful UV-A radiation. Using information from a recently identified gene cluster, we propose a biosynthetic route to this pigment. We also report the characterization of two enzymes, NpR1275 and NpR1276, which are involved in the initial stages of this pathway. A regioselective acyloin reaction between indole-3-pyruvic acid (4) and p-hydroxyphenylpyruvic acid
