Sar guanyl-nucleotide exchange factor activity

id: GO:0005090
name: Sar guanyl-nucleotide exchange factor activity
namespace: molecular_function
type: go
obsolete: False

Description: Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Sar family. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.
