Thermo Scientific Pierce AMAS is an amine-to-sulfhydryl crosslinker that contains NHS-ester and maleimide reactive groups at opposite ends of a very short spacer arm (4.4 angstroms).

Features of AMAS:

Reactive groups: NHS ester and maleimide
Reactive towards: amino and sulfhydryl groups
• Shortest of aliphatic spacer series which includes AMAS, BMPS, GMBS and EMCS
• NHS ester end couples with primary amines at pH 7-9, forming stable amide bonds
• Maleimide reacts with -SH groups at pH 6.5-7.5, forming stable thioether linkages
• Non-cleavable
• Water-insoluble (dissolve first in DMF or DMSO)
• Very short aliphatic spacer has low potential for eliciting an immune response
For Research Use Only. Not for use in diagnostic procedures.

Abstract
Dual binding mode of the nascent polypeptide-associated complex reveals a novel universal adapter site on the ribosome.
Authors:Pech M, Spreter T, Beckmann R, Beatrix B
Journal:J Biol Chem
PubMed ID:20410297
'Nascent polypeptide-associated complex (NAC) was identified in eukaryotes as the first cytosolic factor that contacts the nascent polypeptide chain emerging from the ribosome. NAC is present as a homodimer in archaea and as a highly conserved heterodimer in eukaryotes. Mutations in NAC cause severe embryonically lethal phenotypes in mice, Drosophila ... More
Analysis of RovA, a transcriptional regulator of Yersinia pseudotuberculosis virulence that acts through antirepression and direct transcriptional activation.
Authors:Tran HJ, Heroven AK, Winkler L, Spreter T, Beatrix B, Dersch P
Journal:J Biol Chem
PubMed ID:16257976
'The transcription factor RovA of Yersinia pseudotuberculosis and analogous proteins in other Enterobacteriaceae activate the expression of virulence genes that play a crucial role in stress adaptation and pathogenesis. In this study, we demonstrate that the RovA protein forms dimers independent of DNA binding, stimulates RNA polymerase, most likely via ... More
A central role for the T1 domain in voltage-gated potassium channel formation and function.
Authors:Strang C, Cushman SJ, DeRubeis D, Peterson D, Pfaffinger PJ
Journal:J Biol Chem
PubMed ID:11312262
To interpret the recent atomic structures of the Kv (voltage-dependent potassium) channel T1 domain in a functional context, we must understand both how the T1 domain is integrated into the full-length functional channel protein and what functional roles the T1 domain governs. The T1 domain clearly plays a role in ... More
Spatial and dynamic interactions between phospholamban and the canine cardiac Ca2+ pump revealed with use of heterobifunctional cross-linking agents.
Authors:Chen Z, Stokes DL, Rice WJ, Jones LR
Journal:J Biol Chem
PubMed ID:12972413
Heterobifunctional thiol to amine cross-linking agents were used to gain new insights on the dynamics and conformational factors governing the interaction between the cardiac Ca2+ pump (SERCA2a) and phospholamban (PLB). PLB is a small protein inhibitor of SERCA2a that reduces enzyme affinity for Ca2+ and thereby regulates cardiac contractility. We ... More
