==STRUCTURE OF DIFERRIC BUFFALO LACTOFERRIN==
-
The three-dimensional structure of diferric buffalo lactoferrin has been, determined at 3.3 A resolution. The structure was solved by molecular, replacement using the coordinates of diferric human lactoferrin as a, search model and was refined by simulated annealing (X-PLOR). The final, model comprises 5316 protein atoms for all 689 residues, two Fe(3+) and, two CO(3)(2-) ions. The final R factor was 21.8% for 11 711 reflections in, the resolution range 17.0-3.3 A. The folding of buffalo lactoferrin is, essentially similar to that of the other members of the transferrin, family. The significant differences are found in the dimensions of the, binding cleft and the interlobe orientation. The interlobe interactions, are predominantly hydrophobic in nature, thus facilitating the sliding of, ... [[http://ispc.weizmann.ac.il/pmbin/getpm?10818344 (full description)]]

== Function ==
 +
[https://www.uniprot.org/uniprot/TRFL_BUBBU TRFL_BUBBU] Transferrins are iron binding transport proteins which can bind two Fe(3+) ions in association with the binding of an anion, usually bicarbonate. The lactotransferrin transferrin-like domain 1 functions as a serine protease of the peptidase S60 family that cuts arginine rich regions. This function contributes to the antimicrobial activity (By similarity).
