Hi, I write to ask a question about the LH2 system in Rs. Molischianum. I find the structure from a protein data bank with Protein ID 1LGH, I find that the Mg to Mg distance for intra-dimer is 9.36A while 8.78A for inter-dimer. However, I find that a paper published by Sturcture, it states that the distances are 9.2A and 8.9A, respectively. So which one is correct? Or both are correct? Thanks for anyone who can help. Best regards, Andy
