NUCLEOTIDES IN ASPERGILLUS ORYZAE

Abstract

By an application of gradient elution system of anion exchange chro-matography, acid-soluble nucleotides of Aspergillus oryzae were examined.
The nucleotides which have been universally found in yeast cells and animal tissues, exist also in the fungal cells ; CMP, AMP, UMP, CDP, ADP, CTP, ATP, UTP, GTP, TPN, and UDP-acetyl hexosamine. And the cells contains another unknown nucleotide having uridine base. ATP, ADP, and UDPAH exist in relatively large amounts compared with the others.
The helpfull aids of Dr. Y. Takagi, Medical School of Osaka University, and of Dr. Y. Imanaga, Nara Woman's University, on the assay of acetyl hexosamine, are gratefully acknowledged.
