The religious affairs directorate, Diyanet, said in a statement that 2,560 people have been suspended in the latest wave, bringing the total dismissed to 3,672 since July 15.
Diyanet, which is directly linked to the prime minister's office, was established in 1924 to control religion in officially secular modern Turkey.
The agency has a budget larger than many ministries including health and takes care of close to 80,000 mosques in the predominantly Muslim country.
Diyanet said "the commission created for this purpose (to find Gulen sympathisers) continued its rigorous work".
