I used the brendaDb to extract references for some enzymatic functions detected in a microbial analysis.

EC  refID   title   pubmed
EC:2.5.1.3  1   Camiener, G.W.; Brown, G.M.: The biosynthesis of thiamine. 2. Fractionation of enzyme system and identification of thiazole monophosphate and thiamine monophosphate as intermediates. J. Biol. Chem. (1960) 235, 2411-2417.    13807175
EC:1.1.1.305    1   Gatzeva-Topalova, P.Z.; May, A.P.; Sousa, M.C.: Crystal structure of Escherichia coli ArnA (PmrI) decarboxylase domain. A key enzyme for lipid A modification with 4-amino-4-deoxy-L-arabinose and polymyxin resistance. Biochemistry (2005) 43, 13370-13379.   15491143
EC:2.1.2.13 1   Gatzeva-Topalova, P.Z.; May, A.P.; Sousa, M.C.: Crystal structure and mechanism of the Escherichia coli ArnA (PmrI) transformylase domain. An enzyme for lipid A modification with 4-amino-4-deoxy-L-arabinose and polymyxin resistance. Biochemistry (2005) 44, 5328-5338. 15807526


BrendaDb returns the reference and PubMed id of some publications associated with the enzyme process (EC or KO code), I have filtered functions to "just" 200 via differential analysis but still I want to know which of those are the most relevant. For each function, like EC:3.4.11.18, there are up to 200 references, and it could be very long and fruitless to manually look up all the ~14000 references I have in total. Some of these references are from other organisms, like studies in tomatoes or humans.

Using the original citation, I could search in literature databases (via {fulltext}, {tidypmc} or {europepmc}) and try to find which of them are from microorganisms (scanning for organisms names retrieved via {taxadb}). But I would want to avoid developing my own method if this already exists somewhere.

Is there a method/function, within brendaDb or outside, to filter these publications by organism?
