Comparison of relative abundance (normalized to RecA abundance) of different metabolic genes sequences in mat and sediment metagenomes. For one-carbon cycling: pmoA (particulate methane monooxygenase), mmox (soluble methane monoxygenase), mxaF/xoxF (methanol dehydrogenases), gmaS (gamma-glutamylmethylamide synthetase), mauA (methylamine dehydrogenase) and mcrA (methyl coenzyme M reductase)
