The genome size is 3.6 Mbp, G+C percentage is 43.29%, with 98.43% completeness and 2.52% contamination. A single plasmid of 20,255 bp was detected. The closest relative to strain CLA-AA-H190 was Coprococcus catus (96.76%) based on 16S rRNA gene analysis. ANI comparison identified CLA-AA-H190 as a novel species within the genus Coprococcus, with an ANI value of 90.25% against the closest relative C. catus. GTDB-Tk classification as ‘Coprococcus_A catus_A’ confirmed the proposition of a novel species, but also suggests that separation of Coprococcus into multiple genera could occur in future. Functional analysis showed the strain has 119 transporters, 18 secretion genes, and predicted utilization of starch and production of propionate, butyrate, acetate, cobalamin, and folate. In total, 122 CAZymes were identified, with 19 different glycoside hydrolase families and 13 glycoside transferase families represented. The strain CLA-AA-H190 (phylum Bacillota, family Lachnospiraceae) was isolated from human faeces.
