Mammalian Liver tissue: X
16
(note: no ATP required!)
17
Glycogenin: catalyzes glucose transfer from UDP-glucose (red) to tyr 194 (blue); Mn 2+ (green) required to stabilize UDP leaving group
19
Rabbit muscle Phosphorylase Kinase γ (catalytic) subunit active fragment complexed with ATP and a heptapeptide (RQMSFRL).
20
Phosphorylase kinase δ subunit (calmodulin)
21
As with glycogen phosphorylase: (a) phosphorylase kinase found in two isoforms in both muscle/liver tissues either active or inactive for glycogen breakdown (b) these isoforms differed by phosphorylation
23
Catalytic (C) subunit of mouse protein kinase A (PKA) complexed with ATP and a peptide inhibitor (Ser→Ala)
24
Regulatory (R) subunit of bovine protein kinase A (PKA) complexed with 2 cyclic-AMP molecules (activate C*R dissociation)
