人醛脱氢酶同工酶(ALDHs; EC 1.2.1.3)在前眼组织中表现出非常高的活性。人类角膜ALDH1和ALDH3同工酶是主要的可溶性蛋白(分别占角膜可溶性蛋白的3%和5%),可能在保护角膜免受紫外线辐射(UVR)诱导的组织损伤中发挥重要作用,并直接参与紫外线B (UV-B)光接受。人的晶状体表现出高水平的ALDH1活性(晶状体可溶性蛋白的1-2%)和低水平的ALDH3活性。动力学分析支持这些酶在眼部组织中过氧化醛代谢中的作用。
Human aldehyde dehydrogenase isozymes (ALDHs; EC 1.2.1.3) exhibit very high levels of activity in anterior eye tissues. Human corneal ALDH1 and ALDH3 isozymes are present as major soluble proteins (3% and 5%, respectively, of corneal soluble protein) and may play major roles in protecting the cornea against ultraviolet radiation (UVR)-induced tissue damage, as well as contributing directly to ultraviolet B (UV-B) photoreception. The human lens exhibits high levels of ALDH1 activity (1-2% of lens-soluble protein) and lower levels of ALDH3 activity. Kinetic analyses support a role for these enzymes in the metabolism of peroxidic aldehydes, which have been reported in ocular tissues.
