The Enzyme No One Mentions—and Why That Just Changed
A colleague once described the tricarboxylic acid cycle as a dinner party where three guests do all the talking. Citrate synthase gets the opening anecdote. Isocitrate dehydrogenase, with its famous glioma mutations, commands the center of the table. Succinate dehydrogenase, that dual citizen of the TCA cycle and the electron transport chain, provides the tumor suppressor gravitas. And α-ketoglutarate dehydrogenase? It sits quietly at the far end, generating NADH, committing carbon to the cycle’s oxidative half, and attracting roughly zero attention from anyone except the handful of labs that have tried—and frequently failed—to measure its activity directly. That neglect is not proportional to the enzyme’s biological significance. α-KGDH catalyzes the irreversible oxidative decarboxylation of α-ketoglutarate to succinyl-CoA, simultaneously reducing NAD⁺…
The Enzyme That Sits at the Crossroads—and How to Finally Measure It
A postdoctoral fellow in a mitochondrial disease lab once told me something that has stayed lodged in my memory for years. Her lab had spent eighteen months characterizing a novel SDHB variant identified in a family with aggressive paraganglioma. They had western blots confirming subunit expression. They had immunofluorescence showing mitochondrial localization. They had succinate and fumarate measurements by mass spectrometry. What they did not have, and what reviewers kept asking for, was direct enzymatic activity data. Not a succinate-to-fumarate ratio—which can shift for reasons entirely unrelated to SDH—but actual conversion rate. The kind of number that tells you whether the mutant enzyme still works, works partially, or has become a structural placeholder in the inner mitochondrial membrane. The question…

The Activity No One Actually Measures—Until KTB1124
If you ask any metabolism lab to sketch glycolysis and circle the committed step, the marker lands on PFK-1 without hesitation. If you then ask whether they actually measured PFK-1 activity in their last experiment, the silence is predictable. Glucose uptake is not PFK activity. Lactate production is not PFK activity. Extracellular acidification is not PFK activity. The field has spent years building mechanistic claims about glycolytic flux on the back of distal readouts, while the enzyme that genuinely controls whether carbon enters the pathway or retreats into storage has remained, far too often, invisible. Counting cars on a highway tells you nothing about the condition of the tollbooth. Abbkine's CheKine™ Micro 6-Phosphofructokinase (PFK) Activity Assay Kit (KTB1124) puts the…
