SLD2_ARATH | function | Plays a major role as delta(8)-fatty-acid desaturase which introduces a double bond at the 8-position in the long-chain base (LCB) of ceramides with or without a hydroxy group at the 4-position. The enzyme produces both the 8E and 8Z isomers (in a 4:1 ratio). This structural modification contributes to the quantitative partitioning of ceramides between the two major sphingolipid classes, glucosylceramides and glycosylinositolphosphoryl ceramides. Sphingolipids are important membrane components involved in environmental stress responses, such as resistance to chilling, and act as cell signaling molecules. |
SLD2_ARATH | similarity | Belongs to the fatty acid desaturase type 1 family. |
SLD2_ARATH | tissue specificity | Highly expressed in flowers and siliques. Expressed at low levels in roots, leaves and stems. |
