Navigation
Below is displayed the entity view of the selected entity. Entity view is shown in the form of scheme expressing relations part of (green), contains (orange), substrate of rule (red) and product of rule (blue). The navigation panel on the left shows the entity in corresponding model and allows you to browse the biological structure of the model. Manipulation with the navigation panel is realized by unfolding the items in the navigation tree and clicking on a requested system level.

Annotations Tab
All the annotation links to relevant databases for the currently selected entity are displayed on the Annotation Tab below the scheme.

Models Tab
The Models Tab displays all models containing selected entity.

Relations Tab
Relations Tab contains information about relations in which selected entity figures. There are several types of relations: part of, contains, partial composition items and full composition items. This tab also contains organism info which is optional.

Rules Tab
Rules tab contains list of rules which contains selected entity.

Processes Tab
This tab contains set of processes in which selected entity is present.

photosystem I [ps1]

A photosystem that contains an iron-sulfur reaction center associated with accessory pigments and electron carriers. In cyanobacteria and chloroplasts, photosystem I functions as a light-dependent plastocyanin-ferredoxin oxidoreductase, transferring electrons from plastocyanin to ferredoxin; in photosynthetic bacteria that have only a single type I photosystem, such as the green sulfur bacteria, electrons can go either to ferredoxin (Fd) -> NAD+ or to menaquinone (MK) -> Cytb/FeS -> Cytc555 -> photosystem I (cyclic photophosphorylation).

Definition in BCS:

p700|achl|chl|fa|fb|fx|a1|a0
chlorophyll a (chl, pigment ligand) emits near infra-red {nir} fluorescence
Rule: chl{*}::ps1::tlm => chl{n}::ps1::tlm + photon{nir}::cell
Details
Rule: ps1(p700{+} | fa{-})::tlm => ps1(p700{n} | fa{n})::tlm + photon{red}::cell
modifier: As the recombination is considred as subsequent backward electron transport from Fa- to P700+ through Fx, A1, A0 and aChl, these enities must be in neutral state to accept the electron and hence they are modifiers of the recombination-
