Redox homeostasis at SAM: a new role of HINT protein.

ScHINT1 was identified at sugarcane SAM using subtractive libraries. Here, by bioinformatic tools, two-hybrid approach, and biochemical assays, we proposed that its role might be associated to control redox homeostasis. Such control is important for plant development and flowering transition, and this is ensured with some protein partners such as PAL and SBT that interact with ScHINT1.

Transcriptomic Response of the Diazotrophic Bacteria Strain PAL5 to Iron Limitation and Characterization of the Regulatory Network.

has been the focus of several studies aiming to understand the mechanisms behind this endophytic diazotrophic bacterium. The present study is the first global analysis of the early transcriptional response of exponentially growing to iron, an essential cofactor for many enzymes involved in various metabolic pathways. RNA-seq, targeted gene mutagenesis and computational motif discovery tools were used to define the regulon.
