Disulfide bonds are believed to increase the stability of the native state by decreasing the conformational entropy of the unfolded state due to the conformational constraints imposed by cross-linking (i. e. decreasing the free energy of the unfolded state).

Although free IAA is the biologically active form of the hormone but toxic in high concentration, the vast majority of auxin in plants is found in a covalently bound state are considered hormonally inactive.

IAA has been found to be conjugated to both high- and low-molecular-weight compounds.

Low-molecular-weight conjugated auxins include esters of IAA with glucose or myo-inositol and amide conjugates such as IAA-N-aspartate.

High-molecular-weight IAA conjugates include IAAglucan

SR Proteins, in its phosphorylated form, the SR protein initially binds to nascent pre-mRNA. When 3′ cleavage and polyadenylation are completed, the adapter protein is dephosphorylated by a specific nuclear protein phosphatase that is essential for mRNP export. Only the dephosphorylated adapter protein can bind the mRNP exporter, thereby coupling mRNP export to correct polyadenylation.
