additional information
hexamer
three homodimers are linked to form a ring-like hexamer
hexamer
-
with an extra N-terminal-linked helix interlinking three dimers, the hexameric architecture is not essential for arginine inhibition but is functionally essential for physiologically relevant arginine control of NAGK
-
possible interaction of enzyme with PII signal proteins in vivo
additional information
-
due to the capacity for self-association the enzyme can exist in different states of aggregation depending on the nature of the ligands and the concentration of phosphate buffer
additional information
-
enzyme hexamer forms a complex with PII signaling protein trimer
additional information
-
in vivo complex of enzyme with signal transduction protein PII
