| evidence for a common siderophore transport system but different siderophore receptors in neurospora crassa. | uptake and competition experiments were performed with neurospora crassa and penicillium parvum by using 14c-labeled coprogen and 55fe-labeled ferrichrome-type siderophores. several siderophores of the ferrichrome family, such as ferrichrome, ferricrocin, ferrichrysin, and tetraglycyl-ferrichrome as well as the semisynthetic ferricrocin derivatives o-(phenyl-carbamoyl)-ferricrocin and o-(sulfanilyl-carbamoyl)-ferricrocin were taken up by n. crassa. the ferrichrome-type siderophores used vary in ... | 1985 | 2985545 |
