Define Number of Gene in Metabolic Pathway

Question

[naving2uk]

Hi,

How can we define the number of gene in KEGG human metabolic pathway ?

I used KEGG API "Rest":

operation = 'list/';
database = 'pathway/';
organismCode1 = 'hsa';
pathway_list1 = urlread(strcat(base,operation,database,organismCode1));
pathway_list1 = regexpi(pathway_list1,'[^\n]+','match')';

This is will return the all the pathway for human, how can I define the metabolic pathway with their genes?
