... -aspartic acid, indicating the effectiveness of the uracil pathway. Mutants of black , which lack aspartate decarboxylase, cannot synthesize β-alanine from l -aspartate but can still synthesize it efficiently from uracil. Our findings demonstrate a novel function for pigment cells, which not only screen...

... the protein in the Papilio eye by light and electron microscopic immunohistochemistry using a monospecific antiserum produced against artificially expressed Papilio RBP. We found strong immunoreactivity in the primary as well as secondary pigment cells and in the tracheal cells. The pigment cells have long...
