Functions of Type II Thioesterases in Bacterial Polyketide Biosynthesis.

abstract：:Nucleobindin-2 is a 420 amino acid EF-hand Ca²⁺ binding protein that can be further processed to generate an 82 amino terminal peptide termed Nesfatin-1. To examine the function of secreted Nucleobindin-2 in adipocyte differentiation, cultured 3T3-L1 cells were incubated with either 0 or 100 nM of GST, GST-Nucleobindi...
