Extended Data Fig. 7: Identification of coenzyme M derivatives in cultures by HPLC-MS/MS based on the corresponding retention times.
From: Non-syntrophic methanogenic hydrocarbon degradation by an archaeal species

a and b, hexadecyl-CoM and the corresponding 3 characterized fragments (in blue) in cell extracts from cultures with hexadecane (C16H34) addition. c and d, eicosyl-CoM and 3 characterized fragments (in blue) in cell extracts from cultures with eicosane (C20H42) additions. Standard appears in black primary anions and second anions (produced by fragmentation) detected in hexadecane and eicosane cultures showed the same retention time as the synthetic standards of hexadecyl-CoM and eicosyl-CoM, respectively.
