EC 2.7.2.7 Details

show Brenda entry

EC number

2.7.2.7

Accepted name

butyrate kinase

Reaction

ATP + butanoate = ADP + butanoyl phosphate

Systematic name

ATP:butanoate 1-phosphotransferase

CAS registry number

37278-14-1

Comment

The enzyme from Clostridium sp. also acts, more slowly, on pentanoate and propanoate, and on some branched-chain fatty acids (cf. EC 2.7.1.14 sedoheptulokinase).

History

created 1972, modified 1986, modified 1990
