2.7.1.33 ATP + (R)-4-phosphopantoate + beta-alanine the enzyme is involved in coenzyme A biosynthesis in the archaea 2.7.1.33 ATP + (R)-pantothenate - 2.7.1.33 ATP + (R)-pantothenate first step in coenzyme A biosynthesis 2.7.1.33 ATP + (R)-pantothenate first step in coenzyme A biosynthesis, regulatory function 2.7.1.33 ATP + (R)-pantothenate first step in coenzyme A biosynthesis, the enzyme has a regulatory function in the pathway 2.7.1.33 ATP + (R)-pantothenate coaX is essential for growth of Bacillus anthracis 2.7.1.33 ATP + D-pantothenate - 2.7.1.33 ATP + D-pantothenate first and rate-controlling reaction of CoA-biosynthesis 2.7.1.33 ATP + N-heptylpantothenamide substrate is converted to the inactive butyldethia-CoA analogue in the further downstream pathway leading to grwoth inhibition of the organism, overview 2.7.1.33 ATP + pantothenate first step of the pathway from pantothenate to CoA. The activity of this protein is tightly regulated by CoA feedback inhibition, both in vitro and in vivo
