A temperature-sensitive mutant (ts3) of Newcastle disease virus was physiologically characterized. All major viral structural proteins were synthesized at the permissive (37 degrees C) and nonpermissive (42 degrees C) temperatures, but the fusion (F) glycoprotein was not cleaved at 42 degrees C. In immunocytochemical electron microscopy, the F protein was abundant in the rough endoplasmic retic...

The effects of spermidine analogues [norspermidine (NSPD, 33), spermidine (SPD, 34), homospermidine (HSPD, 44) and aminopropylcadaverine (APCAD, 35)] on cell growth were studied using Escherichia coli polyamine-requiring mutant MA261. Cell growth was compared at 32°C, 37°C, and 42°C. All four analogues were taken up mainly by the PotABCD spermidine-preferential uptake system. The degree of stim...
