Phosphorylation of membrane proteins in response to temperature in an Antarctic Pseudomonas syringae
Temperature-dependent phosphorylation and dephosphorylation of membrane proteins was studied in vitro in a number of psychrotrophic Antarctic bacteria which grow between 0 and 30 °C. One of them, a Pseudomonas syringae isolate, was studied in detail and was found to have three membrane proteins of m...
