Sodium glucose co-transporters SGLT harness the electrochemical gradient of sodium to drive the uphill transport of glucose across the plasma membrane.

Glucose transport across the cell membrane is mediated by two types of transporters: facilitative glucose transporters gene name: solute carrier 2A and sodium—glucose cotransporters SGLTs; gene name: solute carrier 5A. Each transporter has its own substrate specificity, distribution, and regulatory mechanisms. Sodium—glucose cotransporter 1 and sodium—glucose cotransporter 2 have attracted much attention as therapeutic targets for various diseases. In mammals, glucose movement into and out of cells is achieved by glucose transporters GLUTs on the cell membrane. GLUTs are divided into two structurally and functionally distinct types: i GLUTs, which operate by facilitated diffusion 1 , 2 ; and ii sodium—glucose cotransporters SGLTs , which actively transport glucose against the concentration gradient by coupling with sodium 3 , 4. GLUTs are located in all body cells to facilitate transport of glucose into the cells, and the concentrations of glucose into and out of the cells become equal with GLUTs operation 1. In the SGLTs, which comprise a family of at least six different isoforms in humans, glucose and sodium are simultaneously cotransported into the cells using the sodium concentration gradient 5.

The sodium glucose cotransporter 1 is classified as an integral membrane protein that is made up of 14 alpha-helices constructed from the folding of amino acid residues with both the N and C-terminal residing upon the extracellular side of the plasma membrane. Glucose transporters are integral membrane proteins that mediate the transport of glucose and structurally related substances across cellular membranes. Two families of glucose transporter have been identified: the facilitated diffusion glucose transporter family GLUT family , also known as uniporters , and the sodium-dependent glucose transporter family SGLT family , also known as cotransporters or symporters. The sodium glucose cotransporter is original arranged with an outward-facing conformation with open receptors in preparation for 2 sodium ions and glucose to simultaneously bind. Co-transport proteins of mammalian cell membranes had eluded efforts of purification with classical biochemical methods until the late s. The rabbit form of SGLT1 was the first mammalian co-transport protein ever to be cloned and sequenced, and this was reported in

Glucose is a primary energy source in living cells. The discovery in s that a sodium gradient powers the active uptake of glucose in the intestine 1 heralded the concept of a secondary active transporter that can catalyse the movement of a substrate against an electrochemical gradient by harnessing energy from another coupled substrate. SGLTs are responsible for active glucose and galactose absorption in the intestine and for glucose reabsorption in the kidney 4 , and are targeted by multiple drugs to treat diabetes 5. Several members within the SGLT family transport key metabolites other than glucose 2. The structures, together with molecular dynamics simulations and functional studies, define the architecture of SGLTs, uncover the mechanism of substrate binding and selectivity, and shed light on water permeability of SGLT1. These results provide insights into the multifaceted functions of SGLTs. The Author s , under exclusive licence to Springer Nature Limited.

I was close — oh, so close — when I collapsed just outside the stadium with less than one kilometre of the marathon to go. As a biochemistry student, I should have known better, but I had made the mistake of selecting water instead of the electrolyte drinks offered, and so ended up inside an ambulance dehydrated and embarrassed. The discovery that the transport of glucose and sodium ions from the digestive tract into the body is coupled and facilitates the absorption of water was a breakthrough of the twentieth century 1. A simple salt—glucose mixture has since saved millions of lives, and kept runners from collapsing — well, mostly.
