Hi! Can someone please help me by showing me how I can see a pathway with all reactants in KEGG?

For instance, I'm interested in seeing all reactants involved in Glutamate and Glutamine biosynthesis in E. coli. However, in the pathway map some of the reactants (namely, NADPH or NADH) are not shown:

(link: http://www.genome.jp/kegg-bin/show_pathway?org_name=eco&mapno=00250)

(L-glutamate and L-glutamine are near the bottom of the figure)

Alternatively, I would be fine with searching reaction by reaction. For instance, by highlighting enzyme 1.4.1.4 I can extract the reaction identified from the figure above (in the website): R00248 (link: http://www.genome.jp/dbget-bin/www_bget?rn:R00248). But this is not organism specific (or is it?) and it's not very easy to do for many reactions. So, long story short, if I have to extract reaction by reaction how can I search the reactions of my interest?

Sorry if these are very simple questions, I'm new to using KEGG
