BioCyc Databases is available in University of Helsinki until 28.12.
The BioCyc databases are divided into three tiers, based on their quality.
Tier 1 databases have received at least one person-year of literature-based curation, and are the most accurate. EcoCyc and MetaCyc have each received more than 20 person-years of curation.
Tier 2 and Tier 3 databases contain computationally predicted metabolic pathways, predictions as to which genes code for missing enzymes in metabolic pathways, and predicted operons.
The development of BioCyc is funded by NIH grant GM080746 from the NIH National Institute of General Medical Sciences.
