The so called ten celebrated start with K387. K421 is in D Minor whatever you're database says. The A major is K464. The set of six that include 387 & 421 are the quartets that he dedicated to Haydn and they marked a very significant development in his quartet writing, much influenced by his study of Haydn's Op 33 set. Mozart's 'Haydn' set in turn, I feel, had an equal influence on Haydn's later quartets (Op 76 onwards).
