      Pathway:
1-Phosphatidyl-myo-inositol Metabolism
      Reaction: a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol) + ATP = a 1,2-diacyl- sn-glycero-3-phospho-(1D-myo-inositol-3-phosphate) + ADP + H+
1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol)
+ ATP
= 1,2-diacyl- sn-glycero-3-phospho-(1D-myo-inositol-3-phosphate)
+ ADP
+ H(+)

      Pathway:
      Reaction: a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol-4,5-bisphosphate) + ATP = a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol-3,4,5- trisphosphate) + ADP + H+

   Enzyme class 4: E.C.2.7.11.1  - non-specific serine/threonine protein kinase.
[IntEnz]   [ExPASy]   [KEGG]   [BRENDA]
      Reaction:
1. L-seryl-[protein] + ATP = O-phospho-L-seryl-[protein] + ADP + H+
2. L-threonyl-[protein] + ATP = O-phospho-L-threonyl-[protein] + ADP + H+
L-seryl-[protein]
+ ATP
= O-phospho-L-seryl-[protein]
+ ADP
+ H(+)
L-threonyl-[protein]
+ ATP
= O-phospho-L-threonyl-[protein]
+ ADP
+ H(+)
Note, where more than one E.C. class is given (as above), each may correspond to a different protein domain or, in the case of polyprotein precursors, to a different mature protein.
