Identification of a new sulfoquinovose glycosidase, SqgA, in Arthrobacter sp. strain AK01. (a) Degradation of sulfoquinovosyl diacylglycerol (SQDG; R = acyl) to sulfoacetaldehyde (SA) or sulfolactaldehyde (SLA) by sulfoglycolysis (sulfoglycolytic Embden–Meyerhof–Parnas (sulfo-EMP); sulfoglycolytic Entner–Doudoroff (sulfo-ED); sulfoglycolytic sulfofructose transaldolase (sulfo-SFT); sulfoglycolytic transketolase (sulfo-TK) pathways) or sulfolysis to sulfite (sulfolytic SQ monooxygenase (sulfo-SMO); and sulfolytic SQ dioxygenase (sulfo-SDO) pathways). (b) Growth curve of Arthrobacter sp. AK01 grown on equimolar concentration (5 mM) of glucose, sulfoquinovose (SQ), sulfoquinovosyl glycerol (SQGro), or MeSQ. An independent replicate is shown in Figure S3. (c) Comparative proteomics of Arthrobacter sp. AK01 grown on glucose or SQ. (d) Gene cluster encoding the sulfo-EMP pathway for Arthrobacter sp. AK01.
