Pathway Map. Pathway Map view in Genome Projector is based on the Roche Biochemical Pathway wall chart, which provides a biochemical context of the reactome and metabolome. (A) Here, enzymes are shown in blue letters, coenzymes in red, and other compounds in black. Lines in black represent general pathways, red represents unicellular organisms and fungi, blue represents animals, and green represents higher plants. Orange lines show regulatory pathways, accompanied by + or - signs to show activation or downregulation. Key compounds have chemical structures shown in boxes bound by black borders. Every enzyme (in blue text) is clickable to show more detailed information. (B) The overlay layer highlights the organism specific enzymes and pathways by greying out the enzymes that are not annotated in the given organism.
