Assimilatory vs dissimilatory

WebIn the assimilatory sulfate reduction pathway, sulfate is reduced in a stepwise manner to sulfide (S 2-) which is incorporated into amino acids. In the dissimilatory sulfate reduction also the end- product is sulfide. An enzyme ATP-suIfurylase catalyses transfer of sulfate to AMP forming adenosine 5′-phosphosulfate (APS) and pyrophosphate. WebThe recent application of nitrogen stable isotopes as tracers has generated growing evidence that DNRA is a major nitrogen pathway that cannot be ignored. Measurements comparing the importance of denitrification vs. DNRA in 55 coastal sites found that DNRA accounted for more than 30% of the nitrate reduction at 26 sites.
