Ligand Specificity of Bean Leaf Soluble Auxin-binding Protein.
The soluble bean leaf auxin-binding protein (ABP) has a high affinity for a range of auxins including indole-3-acetic acid (IAA), alpha-napthaleneacetic acid, phenylacetic acid, 2,4,5-trichlorophenoxyacetic acid, and structurally related auxins. A large number of nonauxin compounds that are nevertheless structurally related to auxins do not displace IAA from bean ABP. Bean ABP has a high affini...
متن کاملA soluble auxin-binding protein from Hyoscyamus muticus is a glutathione S-transferase.
We have used the photoaffinity label azido-[3H]IAA (5-N3-[7-3H]indole-3-acetic acid), a biologically active analog of indole-3-acetic acid, to identify auxin-binding proteins (ABPs) in the soluble fraction of Hyoscyamus muticus. A 25-kD polypeptide previously described (H. Macdonald, A. M. Jones, P. J. King [1991] J Biol Chem 266: 7393-7399) has now been purified to homogeneity by conventional ...
متن کاملRevisiting Apoplastic Auxin Signaling Mediated by AUXIN BINDING PROTEIN 1
It has been suggested that AUXIN BINDING PROTEIN 1 (ABP1) functions as an apoplastic auxin receptor, and is known to be involved in the post-transcriptional process, and largely independent of the already well-known SKP-cullin-F-box-transport inhibitor response (TIR1) /auxin signaling F-box (AFB) (SCF(TIR1/AFB)) pathway. In the past 10 years, several key components downstream of ABP1 have been ...
متن کاملProperties of soluble somatostatin-binding protein.
A soluble somatostatin-binding protein was detected in the cytosol fractions of various rat, human and bovine tissues. Maximum binding occurred at pH8.0-8.5 and was Ca(2+)-dependent. The specific binding of somatostatin per 10mug of cytosol protein from 12 rat tissues ranged between 36 and 15%, and 3% for peripheral blood cells. There was also substantial binding in cytosol from human anterior ...
متن کاملThe AUXIN BINDING PROTEIN 1 Is Required for Differential Auxin Responses Mediating Root Growth
BACKGROUND In plants, the phytohormone auxin is a crucial regulator sustaining growth and development. At the cellular level, auxin is interpreted differentially in a tissue- and dose-dependent manner. Mechanisms of auxin signalling are partially unknown and the contribution of the AUXIN BINDING PROTEIN 1 (ABP1) as an auxin receptor is still a matter of debate. METHODOLOGY/PRINCIPAL FINDINGS ...
