۶-فسفوفروکتوکیناز، ماهیچه (انگلیسی: 6-phosphofructokinase, muscle type) یک آنزیم است که در انسان توسط ژن «PFKM» واقع بر کروموزوم ۱۵ کُدگذاری میشود. آنزیمهای گروه فسفوفروکتوکیناز، بهطور غیرقابل بازگشت، موجب تبدیل فروکتوز ۶-فسفات به فروکتوز ۱٬۶-بیسفسفات شده و یکی از آنزیمهای تنظیمی مهم در فرایند گلیکولیز محسوب میشوند. چندین فرم مختلف از این آنزیم وجود دارد که در اثر پیرایش دگرسان ایجاد میشوند.[۴]
افزایش بیان ژن PFKM با بروز دیابت نوع ۲ و مقاومت به انسولین در ماهیچههای اسکلتی در ارتباط است.
