A subnetwork with sparsely connected modules detected by SGPG. Module A is enriched in hexokinase activity with p-value 1.71e-5. Module B is enriched in response to endogenous stimulus with p-value 4.77e-5. Module C is enriched in nucleoside phosphate metabolism with p-value 3.43e-6. Patterns I and II are two specific interaction patterns in the subnetwork.
