Page 2: Lines 11-14 should read as follows: ". . .Unlike the genomes of other gammaproteobacterial methanotrophs, the USCγ draft genome contains nearly all essential genes for a complete serine biosynthesis pathway for formaldehyde assimilation. However, the enzymes unique to the typical RUMP pathway, hexulose-6-phosphate synthase and hexulose phosphate isomerase, were not detected. . . .". © 2017 Edwards et al.
