Systematic name YHR096C
Gene name HXT5
Feature type ORF, Verified
Coordinates Chr VIII:296447..294669
Primary SGDID S000001138

Description of YHR096C: Hexose transporter with moderate affinity for glucose, induced in the presence of non-fermentable carbon sources, induced by a decrease in growth rate, contains an extended N-terminal domain relative to other HXTs[1][2][3]

Alleles, Strains, and Phenotypes

Multiple Knockout Strains

Strain Background: CEN.PK2-1C
Genotype: EBY4000 (hxt)
Together with: HXT15, MPH2, HXT7, HXT6, HXT3, HXT13, HXT10, MAL11, HXT4, HXT1, HXT12, HXT8, HXT9, HXT16, MPH3, GAL2, HXT2, HXT14, HXT17, HXT11
Phenotype(s): Viable , Conditionally inviable when on glucose medium

The complete hxt null strain (EBY4000) is unable to take up hexoses and to grow on them. It is well suited to express and characterize heterologous glucose transporters. [4] [5]

DNA and RNA Details

Other DNA and RNA Details

Other Topic: expression

Specifically higher expression in carbon limited chemostat cultures versus carbon excess. [6] [7]

Protein Details

Protein Function/Process

The Hxt5 glucose transporter is one of four Hxt transporters (Hxt4p, Hxt5p, Hxt7p, Gal2p) able to take up xylose [8] [5]
