Hi. I'm trying to get enzyme pH optima from BRENDA by SOAP methods, there's no UniProt ID in output, despite being there in web GUI. Also, nothing is mentioned about UniProt in BRENDA SOAP documentation. Any ideas, please?

my code:

client = Client(wsdl)
parameters = (email, password, "ecNumber*3.1.3.26","phOptimum*", "phOptimumMaximum*", "commentary*", "organism*", "literature*")
resultString = client.service.getPhOptimum(*parameters)
