RT Journal Article SR Electronic(1) A1 Piotrowska, M.YR 1980 T1 Cross-pathway Regulation of Ornithine Carbamoyltransferase Synthesis in Aspergillus nidulans JF Microbiology, VO 116 IS 2 SP 335 OP 339 DO https://doi.org/10.1099/00221287-116-2-335 PB Microbiology Society, SN 1465-2080, AB Regulation of the cross-pathway type was found in Aspergillus nidulans. Ornithine carbamoyltransferase, a biosynthetic enzyme of the arginine pathway, is derepressed as a result of deprivation not only of arginine but also of histidine, proline and tryptophan. Cross-pathway regulation operates in the mutant suD19 in which the ornithine carbamoyl-transferase level is insensitive to arginine. The spectrum of the amino acids involved in this type of regulation seems to be different from those described for other fungi., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-116-2-335
