REMARK 100 REMARK 100 THIS ENTRY HAS BEEN PROCESSED BY RCSB ON 19-OCT-1999. REMARK 100 THE RCSB ID CODE IS RCSB009858.

REMARK 105 REMARK 105 THE PROTEIN DATA BANK HAS ADOPTED THE SACCHARIDE CHEMISTS REMARK 105 NOMENCLATURE FOR ATOMS OF THE DEOXYRIBOSE/RIBOSE MOIETY REMARK 105 RATHER THAN THAT OF THE NUCLEOSIDE CHEMISTS. THE RING REMARK 105 OXYGEN ATOM IS LABELLED O4* INSTEAD OF O1*.

REMARK 220 REMARK 220 EXPERIMENTAL DETAILS REMARK 220 EXPERIMENT TYPE : THEORETICAL MODELLING REMARK 220 REMARK 220 REMARK: HYPOXIA-INDUCIBLE FACTOR-1 (HIF-1) IS A HETERODIMERIC REMARK 220 TRANSCRIPTION FACTOR ACTIVATED BY HYPOXIA. IT IS REMARK 220 COMPOSED OF TWO DIFFERENT SUBUNITS, HIF-1A AND ARNT REMARK 220 (ARYL RECEPTOR NUCLEAR TRANSLOCATOR). THESE TWO SUBUNITS REMARK 220 BELONG TO THE BHLH (BASIC HELIX-LOOP-HELIX) PAS (PER, REMARK 220 AHR/ARNT, SIM) FAMILY. THE BHLH DOMAIN OF THESE FACTORS REMARK 220 IS RESPONSIBLE FOR DIMERIZATION THROUGH THE TWO HELICES REMARK 220 AND FOR DNA BINDING THOUGH THEIR BASIC DOMAIN. WE HAVE REMARK 220 GENERATED A STRUCTURAL MODEL FOR THE INTERACTION OF HIF- REMARK 220 1 DNA BINDING DOMAIN (DBD) WITH HRE USING A MONTE CARLO REMARK 220 PROGRAM CALLED MONTY. PROTEIN-DNA COMPLEXES WERE REMARK 220 GENERATED BY DOCKING THE MODEL OF HIF-1 (DBD) (REF 1) REMARK 220 ONTO THE HRE SEQUENCE. THE COMPLEX WHICH CONTAINED MOST REMARK 220 OF THE CONTACTS OBSERVED IN THE WHOLE SET OF COMPLEXES REMARK 220 WAS CHOSEN AND WAS MINIMIZED USING THE AMBER FORCEFIELD. REMARK 220 THE TWO PROTEINS SUBUNITS HAVE BEEN ASSIGNED CHAIN D AND REMARK 220 C. DNA CHAINS HAVE BEEN ASSIGNED CHAIN INDICATORS A AND REMARK 220 B. THE DNA CHAINS ARE ALIGNED AS FOLLOWS : CHAIN A : 5 REMARK 220 PRIME : GCCCTACGTGCTGC CHAIN B : 3 PRIME : CGGGATGCACGACG
