Sodium-Glucose Cotransporters SGLT mediate the uphill uptake of extracellular sugars and play fundamental roles in sugar metabolism. Although their structures in inward-open and outward-open conformations are emerging from structural studies, the trajectory of how SGLTs transit from the outward-facing to the inward-facing conformation remains unknown.

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 Size-fractionation of large amounts of rabbit intestinal mRNA with preparative gel electrophoresis were then sequentially injected into Xenopus oocytes to ultimately find the RNA species that induced the expression of sodium-glucose cotransport. SLC5A1 is medically relevant because of its role in the absorption of glucose and sodium, however, mutations in the gene can cause medical implications. A missense mutation [4] in the SLC5A1 gene of exon 1 can cause problems creating the SGLT1 protein, leading to a very rare glucose-galactose malabsorption disease. In humans without this genetic disorder, SLGT1 is key to the operation of oral rehydration therapy. By adding sodium and glucose to water, the co-transporter is allowed to transport all three, helping to speed up water absorption. The SLC5A1 cotransporter is mainly expressed in the lumen of the small intestine, kidney, parotid glands, submandibular glands and in the heart.

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

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.

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.
