== Function == | |||
[[http://www.uniprot.org/uniprot/SQASE_ECOLI SQASE_ECOLI]] Catalyzes the hydrolysis of sulfoquinovosyl diacylglycerides (SQDG) to sulfoquinovose (SQ), which is then degraded by E.coli through the SQ Embden-Meyerhof-Parnas (SQ-EMP) sulfoglycolysis pathway as a source of carbon and sulfur. Therefore, is likely involved in the utilization of the sulfoquinovose headgroup found in ubiquitous plant sulfolipids. Is also able to hydrolyze simple sulfoquinovosides such as 1-sulfoquinovosylglycerol (SQGro). Is a retaining glycoside hydrolase, since it forms the alpha anomer of SQ (PubMed:26878550). Also exhibits some alpha-glucosidase activity against alpha-glucosyl fluoride in vitro, although natural substrates, such as alpha-glucobioses are scarcely hydrolyzed (PubMed:15294295).<ref>PMID:15294295</ref> <ref>PMID:26878550</ref> | |||
