The Katon(Fire release) in a nutshell allows the release and handling of the fire, according to various temperatures it change the color of the flame: orange, red, blue ... to the black flames (Amaterasu). Technique that has been classified as the most powerful technique of Katon (I think from the second databook). Amaterasu is created with the katon but it can't be manipulated (see Itachi), because of its high amount of energy that releases. Enton (Blaze release) is like an invisible force/energy that stabilizes and is able to control the flame of Amaterasu. According to this theory the Enton is an element given by the union of Fire + Lightning (lightning is energy). So the Enton is like one of those forces that affect atomic level that can stabilize the amaterasu and controlling it. Being that the Amaterasu and reachable only by the power of sharingan is logical that the Enton is closely connected to the sharingan.
