Calcium modulation of polyamine transport is lost in a putrescine-sensitive mutant of Neurospora crassa.

Archives of biochemistry and biophysics - 1 Mar 1991

Davis R H, Ristow J L, Howard A D, Barnett G R

Abstract excerpt

Putrescine transport in Neurospora is saturable and concentrative in dilute buffers, but in the growth medium putrescine simply equilibrates across the cell membrane. We describe a mutant, puu-1, that can concentrate putrescine from the growth medium because the polyamine transport system has los...
