Emacs-like navigation to beginning/end of sentence in text

I think it is a really big advantage of macOS over other operating systems that it supports a lot of Emacs navigating keyboard shortcuts out of the box. (^ ControlP, ^ ControlN, ^ ControlK, ^ ControlY, you name it...) One shortcut that I am really missing is the capacity to move to the beginning or end of a sentence in a text (in Emacs this is MetaA/MetaE). I could not find a substitute yet to emulate this behavior in macOS. If someone would know a possibility how to do that I would be really happy!
