Environmental Microbiology, Volume 24, Issue 2, Page 566-582, February 2022., 2022 Summary FurC (PerR) from Anabaena sp. PCC7120 was previously described as a key transcriptional regulator involved in setting off the oxidative stress response. In the last years, the cross‐talk between oxidative stress, iron homeostasis and nitrogen metabolism is becoming more and more evident.

Plant, Cell &Environment, Volume 44, Issue 6, Page 1885-1907, June 2021., 2021 Abstract Nitrogen sources are all converted into ammonium/ia as a first step of assimilation. It is reasonable to expect that molecular components involved in the transport of ammonium/ia across biological membranes connect with the regulation of both nitrogen and central metabolism.

Acta Crystallographica Section D, Volume 77, Issue 3, Page 325-335, March 2021., 2021 The crystal structures of adenylylated and unadenylylated GlnK, a PII protein from Corynebacterium glutamicum, indicate that adenylylation of Tyr51 in the T‐loop does not interfere with the PII‐typical conformational changes that occur in the T‐loop upon effector binding.

Energy Sensing versus 2-Oxoglutarate Dependent ATPase Switch in the Control of Synechococcus PII Interaction with Its Targets NAGK and PipX. [PDF]
PLoS ONE, 2015 PII proteins constitute a superfamily of highly conserved signaling devices, common in all domains of life. Through binding of the metabolites ATP, ADP and 2-oxoglutarate (2-OG), they undergo conformational changes which allow them to regulate a variety ...

Synthesis and Cellular Labeling of Caged Phosphatidylinositol Derivatives
Chemistry – A European Journal, Volume 26, Issue 2, Page 384-389, January 7, 2020., 2020 Important tools in cell biology: A membrane‐permeant caged phosphatidylinositol (PI) derivative featuring a photo‐removable coumarinyl group masking the negative charge of the phosphate, as well as two enzymatically removable butyrate esters for increased lipophilicity and for preventing phosphate migration, were synthesized (see figure).
