Studies on Taste of Ribonucleic Acid Derivatives

Umami Responses in Mouse Taste Cells Indicate More than One Receptor

“…2 B Behavioral and afferent nerve responses to glutamate are synergistically enhanced by the presence of 5Ј-ribonucleotides, a characteristic feature of umami taste (Kuninaka, 1960). Thus, we tested whether glutamate-induced Ca 2ϩ responses were altered by IMP, as expected for umami signals.…”

GENETIC AND BEHAVIORAL INFLUENCES OF QUININE AND MONOSODIUM GLUTAMATE ON Drosophila melanogaster

“…Behavioral and afferent nerve responses to glutamate are synergistically enhanced by the presence of 5-ribonucleotides, a characteristic feature of umami taste (Kuninaka, 1960). The implication is that umami responses may originate from more than a single type of receptor or receptor combination.…”

Production of Nucleic Acid-Related Substances by Fermentative Processes. V. Accumulation of Inosinic Acid by an Adenine-Auxotroph of Micrococcus Glutamicus

“…This led us to an attempt for the use of microbial auxotrophic mutants for the fermentative production of nucleic acid-related substances, some of which have recently received attention as seasoning materials (2)(3)(4). Xanthosine accumulation by Aerobacter aerogenes P 14(5) was observed at a level of 6 mg per ml (6).…”
