FabB
Bacterial fatty acid synthase (FAS) system enzyme, codon optimized for S.Cerevisiae. Part of the FAS2 system from E.coli, see our wiki for an overview of the system.

Usage and Biology
Responsible for the elongation step in fatty acid synthesis, adding another two carbons onto the growing chain and continuing the cycle from initiation or continuation. See FabG for the next step.

Experimental design
By creating a single genetic fragment with FabB and AcpP and their promoters going in the forward and reverse direction, these two genes are easily integrated into the yeast genome using the pCfB3038(XII-1 MarkerFree) plasmid from EasyClone kit (3).
Methodology
Double gene fragment ordered from IDT was cloned using Phusion polymerase according to protocol. Insert was purified following protocol for gel electrophoresis and ThermoFischer gel purification kit, followed by assembly into linearized plasmid backbone. The constructed plasmid was transformed into E.coli, grown overnight, inoculated overnight again, followed by harvesting following protocol for ThermoFischer plasmid miniprep kit. The purified plasmid was digested to yield the linearized insertion fragment and transformed into S.Cerevisiae strain CEN.PK 102-5B along with CAS9 and gRNA plasmids.
