What was the Septuagint’s influence on Greek?

There has long been a debate over the influence of the Greek language and culture on the Septuagint translation of the Hebrew scriptures but little has been said about the influence the latter had on the former. The Greek language gradually changed after Alexander conquered ‘the world’ and Jews played a role in this change. The Hebrew Bible was the way of life for Jews and therefore its translation into Greek would have impacted their use of that language more than that language would have  impacted them. Does anyone know of a study in which this impact is measured; ranging from little things like the use of “en” to translate the Hebrew to bigger things like the use of “kurios” for God?
