Figure 6.5 Alignment of 18 green algae (GA) and cyanobacterial (CYA) TrHb1s using
Chlamydomonas eugametos LI637 Hb as the query. The top line indicates secondary
structure as found in the query protein (PDB ID 1DLY,
Pesce et al., 2000
). Residues in
bold are at positions B10, E10, F8 and H16, as numbered by structural homology to
the canonical 3/3 fold. The proteins and organisms are: TRHN1_CHLMO
Chlamydomonas moewusii (GA); TRHN2_CHLMO Chlamydomonas moewusii (GA);
A8ISP8_CHLRE Chlamydomonas reinhardtii (GA); D8UFV6_VOLCA Volvox carteri (GA);
A8JAR4_CHLRE C. reinhardtii (GA); A8JAR3_CHLRE C. reinhardtii (GA); D8THA8_VOLCA
V. carteri (GA); C1N9B0_MICPC Micromonas pusilla strain CCMP1545 (GA);
A8ISQ0_CHLRE C. reinhardtii (GA); Q8RT58_SYNP2 Synechococcus sp. strain PCC 7002
(CYA); TRHBN_SYNY3 Synechocystis sp. strain PCC 6803 (CYA); K9ZA57_CYAAP Cyano-
bacterium aponinum strain PCC 10605 (CYA); I4HJM1_MICAE Microcystis aeruginosa
PCC 9808 (CYA); I4H5U0_MICAE M. aeruginosa PCC 9807; I4G3L9_MICAE
M. aeruginosa PCC 9443 (CYA); B7K1Y4_CYAP8 Cyanothece sp. strain PCC 8801 (CYA);
C7QR53_CYAP0 Cyanothece sp. strain PCC 8802 (CYA); E1Z454_CHLVA Chlorella
variabilis (GA). Note the absence of
the proximal histidine in Chlamydomonas
reinhardtii A8ISQ0.
