The phrase "alternative transporter" is correct and usable in written English.
You can use it when referring to a different means or method of transportation, especially in contexts related to logistics, shipping, or transportation systems.
Example: "The company is exploring the use of an alternative transporter to reduce costs and improve delivery times."
Alternatives: "substitute carrier" or "different transport method".
For instance, transmembrane gradient formation based on membrane dynamics and alternative transporter molecules (e.g. RNA molecules) have been studied in recent years [ 262- 265].
Using an elegant transgenic mouse model combining GLUT2 knockout (with re-expression of the alternative transporter GLUT1 in pancreatic β-cells to maintain insulin secretion), Thorens' group found reduced glucagon responses to glucoprivation [ 40].
Reduced sulfate uptake is compensated for by increased uptake of cysteine and cysteine-containing compounds (as well as other sulfur-containing compounds) through alternative transporter systems not competitively inhibited by chromate.
The Geobacillus sp. C56-T2 HUS locus does encode an AguA ortholog, but is also missing orthologs of the aguEFG genes, suggesting this strain can also not utilize aldotetraouronic acid as a metabolic intermediate, although it cannot be excluded that an alternative transporter for this substrate may exist in this strain.
Therefore, it appears that there is no compensatory uptake of DA by alternative transporters either in core or shell of the nucleus accumbens of DAT-KO mice.
This suggests that megalin is not rate-limiting for efficient renal Sepp reuptake under these conditions or alternative transporters compensate for its reduction.
Potential alternative transporters like GLUT3 and GLUT4 [ 33] were not investigated in the present study.
These cases likely involve as of yet unidentified alternative transporters in M. tb.
Similarly, alternative transporters such as Fps1 [ 24], Gup1, and Gup2 [ 25] do not seem to be significantly involved in glycerol uptake during growth of S. cerevisiae on glycerol.
Iron accumulation in organisms that live in the ocean environment is difficult [ 26] and the evolution of two alternative transporters could be important in order to survive under different physical conditions.
As a result, BA excretion to the systemic circulation via these alternative transporters could increase dramatically in these mice, leading to the higher plasma level of BAs observed (Table 6).
