Editor's Notes from literature on cGMP Phosphodiesterase (PDE6)

Recent update from: 22.12.99

PDEA1

Notes

2 sites on PDEA-PDEB complex for PDEG binding (A+B)
PDEG site interacting with B overlaps partly GNAT binding site (main site of interaction)
GNAT first reacts with A-site PDEG and removes it into GNAT-PDEG complex
Than GNAT reacts with B site to form a fully active GNAT-PDEA-PDEB-PDEG-GTP complex

PDEG, gamma rod

Notes

Phosphorylated by a kinase of 70 kDa
The kinase does not require any of the known activators
The kinase is cGMP inhibited
PDEG in complex with GNAT is not phosphorylated
80% of PDEG is phosphorylated
PDEG is phosphorylated at Thr22
Phosphorylation increases inhibitory activity on PDEA/B
Dephosphorylation is inhibited by cGMP too
Non-catalytic cGMP binding sites are not involved in PDEG phosphorylation

PDEG, gamma rod

Notes

Phosphorylated PDEG looses interaction to GNAT
Phosphorylated PDEG inhibits PDEA/B more effectively
PDEG inhibits two steps: GTP hydrolysis of GNAT and GDP GNAT reassociation with GNB/G
Excess amonuts of PDEG does not change any GTPase activity
After GTP hydrolysis GNAT still forms a complex with PDEG
